                                "documentation": "ApMatchedPhotom<br>ApMatchedCat<br>v02<br>2012-04-23<br>Mehmet Alpaslan <mehmet.alpaslan@icrar.org><br><br>This catalogue provides Kron and Petrosian photometry for all GAMA DR2<br>objects, as well as other Source Extractor outputs for the ugrizYJHK<br>bands obtained from the v02 mosaics using <a href=\"http://www.astromatic.net/software/sextractor\">Source Extractor</a>.<br><br>The GAMA mosaics have been constructed by stitching together<br>individual frames of images taken from the SDSS and UKIDSS LAS surveys<br>using <a href=\"http://www.astromatic.net/software/swarp\">SWarp</a>, a resampling and co-adding program. There is one mosaic<br>per band and per GAMA survey region. All frames in the mosaics have<br>been pre-convolved to a common seeing of 2 arcsec and renormalised.<br>The pixel scale of these mosaics (and hence of the present catalogue)<br>is 0.339 arcsec per pixel. The zero-point used throughout is 30 mag.<br>The mosaics are available on the <a href=\"/dr2/data/imaging/gama/mosaics/v02/\">DR2 file server</a> (swpci* files).<br><br>The photometry was obtained by using Source Extractor in matched<br>aperture mode. In short, this mode allows Source Extractor to fit an<br>aperture around a possible source in one image, and measure the flux<br>from another. In the present case, we have fit the apertures to r-band<br>images and measure the fluxes in all 9 bands. This process was<br>automated using a wrapper written in <a href=\"http://www.r-project.org/\">R</a> that creates a cutout image of<br>each source in all 9 bands, each of which is fed into Source Extractor<br>alongside the master r-band cutout. Where Source Extractor fails to<br>calculate a magnitude (for whatever reason) the default value returned<br>is 99. Any nonsense results (negative values for FLUX, BACKGROUND or<br>FWHM) are caused by Source Extractor failing; in these cases consult<br>the appropriate FLAGS column to get some indication as to why this is<br>happening.<br><br>Some small areas of the GAMA survey regions are not covered by the<br>YJHK mosaics because some frames in these bands had to be removed due<br>to poor image quality. The YJHK magnitudes and errors of objects<br>located in these areas have been set to -99, while their fluxes and<br>associated errors have been set to 0 and 1E99, respectively.<br><br>#######################################################################<br><br>MAG_AUTO_ / MAG_PETRO_<br><br>The magnitudes presented in this catalogue have not been corrected for<br>the effect of foreground Milky Way dust extinction. Should these<br>corrections be required, they can be obtained from the table<br>GalacticExtinction in the InputCat DMU.<br><br>All photomotry is on the AB system.<br><br>#######################################################################<br><br>Photometric errors<br><br>The errors associated with the MAG_AUTO and MAG_PETRO values have been<br>calculated and rescaled in such a way as to match the errors used in<br>the SDSS and UKIDSS photometry catalogues. To do this, the raw Source<br>Extractor errors have been taken and, for each band, rescaled such<br>that they match these existing photometry catalogues as accurately as<br>possible. The original Source Extractor errors are preserved in the<br>_SE columns.<br><br>########################################################################<br><br>Potential zero-point offsets<br><br>From recent comparisons with VIKING and 2MASS we have discovered an<br>apparent zero-point offset in our photometry derived from the UKIDSS<br>LAS data. The cause of this offset is still not fully understood.<br>This issue will be described in more detail in a future paper<br>presenting the GAMA II panchromatic photometry catalogue (Driver et<br>al., in prep.). In the meantime, users may wish to consider applying<br>the following zero-point offsets to bring the YJHK magnitudes of this<br>catalogue into agreement with VIKING:<br><br>  Y_corr = Y_DR2 - 0.13 mag<br>  J_corr = J_DR2 - 0.12 mag<br>  H_corr = H_DR2 - 0.07 mag<br>  K_corr = K_DR2 - 0.11 mag<br><br>########################################################################<br><br>Dependencies: <br><br>\tInputCat\tTilingCatv16 <br>\tMosaicing\tv02<br><br>#######################################################################<br><br>The Source Extractor parameters used to generate this catalogue are as <br>follows:<br><br>DETECT_MINAREA\t\t16\t<br>Minimum number of pixels above threshold triggering detection.<br><br>DETECT_THRESH\t\t1.7\t<br>Detection threshold relative to background.<br><br>FILTER\t\t\tN\t<br>If true, filtering is applied to the data before extraction.<br><br>DEBLEND_NTHRESH\t\t32\t<br>Number of deblending sub-thresholds. <br><br>DEBLEND_MINCONT\t0.00005\t<br>Minimum contrast parameter for deblending.<br><br>CLEAN_PARAM\t\t0.1<br>Efficiency of cleaning.<br><br>WEIGHT_TYPE\t\tNONE\t<br>Weighting scheme used for weight maps.

This population<br>is defined as all galaxies with M_r(z_ref=0, Q=0.78) < -20.4 mag,<br>where Q defines the expected evolution of M_r as a function of<br>redshift. Q is taken from Loveday et al. (2014, in prep). Given the<br>depth of the GAMA I survey (r < 19.4 mag) the above absolute magnitude<br>limit implies a redshift (i.e. volume) limit of z=0.18333. However, in<br>order to account for the upper edge of the velocity range employed<br>when searching for nearby galaxies (see below), the environment<br>measurements are only provided for galaxies out to z=0.18.

Both are in the<br>same format and the latter is an exact subset of the former. In fact,<br>ExternalSpec is a \"view\" of ExternalSpecAll. It lists only those<br>entries with IS_SBEST = TRUE, meaning that it excludes intra-survey<br>duplicate observations. However, it still includes inter-survey<br>duplications.<br><br>In the following we provide additional information for some of the<br>parameters in these tables:<br><br>SPECID: <br>-------<br>This is the spectrum's unique identifier as used in the GAMA DR2<br>database.

These<br>data cover between 70% and 95% of the three equatorial regions.<br><br><br>Unique area (Primary vs Secondary)<br>==================================<br>GALEX tiles overlap one another. This, of course, is inevitable when<br>trying to cover a contiguous area with circular fields of view.<br>Furthermore, because we include archival survey data which is observed<br>on a sky grid system and pointed observations (which are not on the<br>sky grid system) the overlap is often very hap-hazard. There are<br>several ways to handle this such that we include only unique<br>detections and allow a precise footprint computation. We use a method<br>that optimizes the areal coverage and weights tiles with FUV coverage<br>highest.<br><br>For each GAMA region the GALEX tiles are rank-sorted by FUV exposure<br>time and secondary rank-sorted by NUV exposure time. This ensures that<br>any tile with FUV coverage takes precedence over any tile with only<br>NUV coverage (note that the FUV detector on GALEX is non-operational<br>at this time).<br><br>Once sorted, the footprint of each tile is derived from the relative<br>response map (effective exposure time map) by comparing it to all<br>neighboring tiles with a higher rank-order. In this way a \"primary<br>map\" is made for each tile indicating which parts of the field of view<br>are to be considered \"primary\" and which parts are to be considered<br>\"secondary\".<br><br>In this DMU we only consider the primary areas.<br><br>Note that photometric data from the secondary areas as provided by the<br>GALEX SExtractor-based pipeline are available at the GALEX-GAMA<br>website.<br><br><br>Photometry<br>==========<br>None of the fluxes and magnitudes presented in this DMU have been<br>corrected for the effect of foreground Milky Way dust extinction.<br>Should these corrections be required, they can be obtained from the<br>table <a href=\"/dr2/schema/table.php?name=GalacticExtinction\">GalacticExtinction</a> in the <a href=\"/dr2/schema/dmu.php?name=InputCat\">InputCat DMU</a>. <br><br>All photometry is on the AB system.<br><br>The photomtery produced by the GALEX SExtractor-based pipeline is<br>accompanied by artifact warning flags.

Refer to<br>the table GalexObsInfo for detection limits and to distinguish between<br>GAMA objects that were not detected in the GALEX data and those that<br>were not covered by GALEX.<br><br><br>Description of advanced matching procedure<br>==========================================<br>The advanced matching procedure takes into account the possibility of<br>multiple matches between GALEX and GAMA objects and seeks to<br>reconstruct the true UV flux of a given GAMA object.<br><br>We illustrate the routine for an example GAMA object. First, optical<br>shape information for the object (r-band ellipticity, position angle,<br>and effective radius) is extracted from the catalogue SersicCat,<br>and used to define a target area within which GALEX counterparts will<br>be deemed to be associated with the GAMA object. To take into account<br>scatter in apparent positions from real positions in the UV and<br>possibly unavailable optical shape information, the minimal search<br>region, i.e. optical target area, is a circle of radius 4 arcsec (the<br>matching radius used in GalexSimpleMatch). The question that is then<br>to be answered is which GALEX objects in GalexPhot have their central<br>coordinates within this optically defined search region. The number,<br>the IDs and the total flux of all such GALEX objects are recorded in<br>columns NMATCHUV, UVIDXLIST and FLUXTOT_XXX, respectively.<br><br>Since it is possible that a GALEX object may itself be extended, or<br>that it has more than one potential close-lying optical counterpart in<br>InputCatA, we also need to take into account the possibility that one<br>or more of the GALEX objects in the search region around the GAMA<br>object may themselves be related to further GAMA objects. Hence, in<br>the second step of the advanced matching procedure, a UV area is<br>constructed for each GALEX object within the optical search region,<br>using the object's position angle, ellipticity and size along its<br>semimajor axis from GalexPhot. InputCatA is then searched for GAMA<br>objects within the UV area of each of the GALEX objects. The number<br>and IDs of the GAMA objects found in this step are recorded in the<br>columns NMATCHOPT and OPTIDXLIST^*. The columns NMATCHUV and UVIDXLIST<br>for the GAMA objects found in this step are updated to include this<br>GALEX object.<br><br>In cases where there is a 1-to-1 match all of the flux of the GALEX<br>object is attributed to the matching GAMA object. This is by far the<br>most common case (68%). If, however, there is more than one potential<br>optical counterpart to one or more of the GALEX objects in the optical<br>search region, the UV flux of each of the GALEX objects is split among<br>all potential optical counterparts of that GALEX object, weighted<br>inversely by angular distance (using a minimum distance of 0.3 arcsec<br>to account for positional errors). Finally, the UV flux contributions<br>from all of the GALEX objects in the optical search radius to the GAMA<br>object under consideration are summed up and recorded in the columns<br>FLUXSPLIT_XXX. FLUXSPLITERR_XXX is the square-root of the weighted<br>quadratic sum of the errors of all GALEX objects from which the object<br>under consideration received a flux contribution, where the weights in<br>the quadratic sum are the same weights as those used for the flux<br>itself.<br><br>Finally, we purge from the catalogue all GAMA objects with<br>FLUXSPLIT_NUV / FLUXSPLITERR_NUV < 2.5.<br><br>Note that in cases where there is a 1-to-1 match between a GAMA and a<br>GALEX object we have FLUXTOT_XXX = FLUXSPLIT_XXX. Furthermore, in<br>these cases FLUXTOT_XXX is equal to FLUX_XXX from GalexPhot of the<br>GALEX object identified as the GAMA object's nearest GALEX neighbour<br>in GalexSimpleMatch. In other words, in these \"simple\" cases the<br>advanced matching procedure returns the same result for the UV fluxes<br>of a given GAMA object as the simple nearest neighbour matching.<br><br>Also note that it is possible for a GAMA object not to have a<br>FLUXTOT_XXX value associated with it but to still have a FLUXSPLIT_XXX<br>value associated with it. This will happen if there are no GALEX<br>objects within the GAMA object's optical search region (leading to<br>FLUXTOT_XXX being set to its default value of -99.0) and if the GAMA<br>object lies inside the UV search region(s) of one or more GALEX<br>objects, which in turn lie in the optical search region of at least<br>one other GAMA object. In this case the first GAMA object participates<br>in the re-distribution of the UV flux from these GALEX objects,<br>leading to FLUXSPLIT_XXX values != -99.0.<br><br>We also point out that there are substantial differences between the<br>objects included in this catalogue and those included in<br>GalexSimpleMatch. An object may be included in this catalogue but not<br>in GalexSimpleMatch and vice versa. The former happens when a GAMA<br>object is more than 4 arcsec away from its nearest GALEX neighbour but<br>still receives flux from one or more GALEX objects during the flux<br>re-distribution (with S/N_NUV >= 2.5). The latter happens when the<br>flux redistribution results in the S/N of the NUV flux received by a<br>GAMA object listed in GalexSimpleMatch dropping below the threshold of<br>2.5.<br><br>We recognise that the above flux redistribution scheme may not be<br>optimal, and that users may wish to apply other recipes for<br>distributing the UV flux among the optical counterparts (e.g. using<br>additional prior astrophysical information). This is easily achieved<br>given that we identify all GALEX and GAMA objects involved in a given<br>match in the columns UVIDXLIST and OPTIDXLIST^*.<br><br>We caution that the UV flux estimates reported in columns<br>FLUXSPLIT_XXX are only correct in a statistical sense, i.e. when<br>considering a large population of objects. However, for individual<br>objects they are necessarily imprecise.<br><br>The default value for non-measurements is -99.0.<br><br><br>^* Additional note<br>==================<br>This catalogue is actually slightly inconsistent with the rest of the<br>GAMA DR2 because the advanced matching procedure described above was<br>carried out using v06 of InputCatA, whereas the version released in<br>DR2 is <a href=\"/dr2/schema/table.php?name=InputCatA\">v05</a>. InputCatAv05 is the GAMA I master input catalogue, whereas<br>InputCatAv06 is the version used for GAMA II. v06 was chosen for the<br>advanced matching between GalexPhot and InputCatA because it has a<br>slightly fainter flux limit than v05 (r < 20.0 in v06 vs. r < 19.8 in<br>v05), and because it includes point sources (which were excluded from<br>v05). Both of these differences should make the matching and flux<br>re-distribution more reliable.<br><br>As explained above, column OPTIDXLIST lists all GAMA objects (using<br>the SDSS identifier OBJID) that are involved in the matching. However,<br>since InputCatAv06 contains significantly more objects than v05, a<br>number of the objects listed in column OPTIDXLIST are not found in<br>InputCatAv05 as released in GAMA DR2. To be precise, of the 62,036<br>unique objects listed in column OPTIDXLIST 9686 are not in<br>InputCatAv05. <br><br>Furthermore, we note that InputCatAv05 is based on SDSS DR6, whereas<br>InputCatAv06 is based on SDSS DR7. The SDSS OBJID used in column<br>OPTIDXLIST is hence the SDSS DR7 OBJID. However, since a small<br>fraction of objects changed their SDSS OBJID between DR6 and DR7,<br>there are 546 objects that are listed in column OPTIDXLIST with a<br>different OBJID than that used in InputCatAv05.<br><br>",

We take this information from the most<br>reliable source of shape information for GAMA galaxies, <a href=\"/dr2/schema/table.php?name=SersicCatAll\">SersicCatAll</a><br>in the <a href=\"/dr2/schema/dmu.php?name=SersicPhotometry\">SersicPhotometry DMU</a>.<br><br><br>Description of CoG method<br>=========================<br>For each object to be analysed, the local background level and its<br>(Poissonian) error, sigma_bkg, is estimated in the NUV/FUV data at the<br>object's optical position, and the background is subtracted. An<br>elliptical aperture is constructed from the object's r-band position,<br>effective radius (GAL_RE_R), ellipticity (GAL_ELLIP_R) and position<br>angle (GAL_PA_R) from SersicCatAll. This aperture is then convolved<br>with the GALEX PSF, assumed to be a Gaussian with a FWHM of 5.3 arcsec.<br><br>The flux is then averaged in elliptical annuli of the above shape of<br>width 3 arcsec (as measured along the object's major axis). The<br>\"integration radius\" (along the major axis) of the target is then<br>defined as the smaller of the following: the outer radius of the<br>smallest annulus in which the average flux falls below the background<br>level plus 1.0 sigma_bkg or the outer radius + 3 arcsec of the<br>smallest annulus in which the average flux falls below the background<br>level plus 1.5 sigma_bkg. This was found to be a good compromise<br>between including very faint target emission at large radii on the one<br>hand and the need to avoid pure noise integration or blending with<br>neighbouring objects on the other. This integration radius is listed<br>in columns RE_CRIT_XXX in the catalogue.<br><br>Objects for which the flux in the innermost annulus (0-3 arcsec) is<br>already below the level of the background plus 1.5 sigma_bkg have<br>RE_CRIT_XXX set to 0. Furthermore, objects with RE_CRIT_XXX = 3 arcsec<br>must also be considered non-detections since they are smaller than the<br>GALEX PSF.<br><br>The flux of the target is then determined by integrating the flux<br>inside the elliptical aperture of size RE_CRIT_XXX. If this flux is<br>negative (i.e. a complete non-detection) then all flux columns are set<br>to 99. Note that apart from this \"cut\", all flux measurements are<br>reported in this catalogue, i.e. no S/N limit is applied.<br><br>In order to avoid contamination from neighbouring sources (taken from<br>InputCatA), a circular area with a radius (not diameter) of 5.3 arcsec<br>is masked around these. Any masked pixels inside a galaxy's<br>integration aperture are accounted for by renormalizing the unmasked<br>galaxy flux measured in the same elliptical annuli as the masked<br>pixels. Galaxies where this was necessary are flagged in the columns<br>CONFSOURCE_XXX. Objects for which the flux profile never reaches the<br>level of the background plus 1.5 sigma_bkg due to the flux of<br>neighbouring objects outside of their masks have their fluxes set to<br>999. Objects with a masked area in the central radius bin are deemed<br>to be unmeasurable and their flux values are set to -99.<br><br>Objects with RE_CRIT_NUV > RE_CRIT_FUV + 30 arcsec are very likely to<br>have a NUV measurement that was contaminated by a neighboring<br>source. (Especially stars tend to be much fainter in the FUV, thus<br>even very bright stars are very unlikely to have excess FUV flux<br>outside the masked area, even though they may have excess NUV flux<br>outside the masked area.) Therefore, all NUV columns are set to 999 in<br>these cases.<br><br>Objects not covered by the GALEX data (or those where the coverage of<br>the surroundings was not sufficient for a background estimate) also<br>have their fluxes set to -99.<br><br>",

It reproduces<br>the most important information from the other catalogues in this DMU<br>and provides a best estimate of the NUV and FUV fluxes of all GAMA DR2<br>objects that were detected by GALEX.<br><br>Included in this catalogue are all GAMA DR2 objects that either<br><br>- have an entry in GalexSimpleMatch<br>or<br>- have an entry in GalexAdvancedMatch<br>or<br>- have an entry in GalexCoGPhot with S/N_NUV >= 2.5 and integration<br>  radius RE_CRIT_NUV >= 6 arcsec<br><br>The S/N criterion applied to GalexCoGPhot is the same as that used for<br>GalexPhot and GalexAdvancedMatch. Note that GAMA DR2 objects that were<br>not detected by GALEX (in the sense that they do not match any of the<br>criteria above) are not included in this catalogue. Refer to the table<br>GalexObsInfo for nominal detection limits and to distinguish between<br>GAMA objects that were not detected in the GALEX data and those that<br>were not covered by GALEX. For DR2 objects not included in the present<br>catalogue you can also turn to the table GalexCoGPhot to find out if<br>they were \"detected\" at S/N_NUV < 2.5, i.e. essentially to find upper<br>flux limits for these objects.<br><br>This catalogue provides the following information:<br><br>- In columns 50-75 (NN_GGOID - NN_POSANGERR_NUV) we reproduce the main<br>  information on the GAMA object's nearest neighbour GALEX object from<br>  GalexPhot (catalogue of UV detections and photometry from the GALEX<br>  SExtractor-based pipeline), using GalexSimpleMatch to connect the<br>  two. The columns NN_FLUX_XXX contain the fluxes of the nearest<br>  neighbour GALEX object as measured by the GALEX SExtractor-based<br>  pipeline. For more information refer to the notes of the<br>  GalexSimpleMatch and GalexPhot tables.<br><br>- In columns 16-35 (NMATCHUV - SPLIT_MAGERR_FUV) we reproduce the main<br>  information from GalexAdvancedMatch. This table contains the result<br>  (for GAMA DR2 objects) of an advanced match between GalexPhot and<br>  InputCatA. The advanced matching procedure attempts to reconstruct<br>  the true UV flux of a given GAMA object in cases where multiple GAMA<br>  and GALEX objects are associated with each other. This reconstructed<br>  flux is reported in columns SPLIT_FLUX_XXX. The columns TOT_FLUX_XXX<br>  contain the total flux of all GALEX objects associated with a given<br>  GAMA object. For more information refer to the notes of the<br>  GalexAdvancedMatch table.<br><br>- In columns 36-49 (COG_FLUX_NUV - COG_CONFSOURCE_FUV) we reproduce<br>  the main information from GalexCoGPhot. This table contains<br>  photometric measurements (using a curve-of-growth method) at the a<br>  priori known optical positions of GAMA objects. The columns<br>  COG_FLUX_XXX contain the fluxes returned by the CoG method. For more<br>  information refer to the notes of the GalexCoGPhot table.<br><br>- In columns 7-15 (BEST_FLUX_NUV - BEST_METHOD) we report our best<br>  estimate of the NUV and FUV fluxes of a given GAMA object. In these<br>  columns we make appropriate choices among the various fluxes<br>  available for a given object (from the advanced matching or CoG<br>  methods), and we strongly recommend the use of these BEST fluxes.<br><br>  In cases where there is an unambiguous 1-to-1 correspondence between<br>  a GAMA and a GALEX object we believe the fluxes returned by the<br>  GALEX pipeline for the GALEX object to be the most appropriate. Note<br>  that in these cases the nearest neighbour and advanced matching<br>  procedures of course return the same results for the UV fluxes of a<br>  given GAMA object, i.e. NN_FLUX_XXX = TOT_FLUX_XXX = SPLIT_FLUX_XXX.<br>  <br>  In cases where the GAMA object is very extended or where there are<br>  multiple GAMA and/or GALEX objects associated with each other we<br>  believe our CoG photometry to be superior. <br><br>  However, in cases where the CoG measurements have failed (for<br>  whatever reason, see the notes of the GalexCoGPhot table) we resort<br>  to the reconstructed fluxes SPLIT_FLUX_XXX returned by the advanced<br>  matching procedure.<br><br>  We therefore set BEST_FLUX_XXX according to the following rules: <br><br>  - If only one of COG_FLUX_NUV and SPLIT_FLUX_NUV is available in<br>    this catalogue then the BEST columns are set to the corresponding<br>    columns of the available flux method.<br><br>  - If both COG_FLUX_NUV and SPLIT_FLUX_NUV are available in this<br>    catalogue then the BEST columns are set to the corresponding<br>    columns of the CoG method if NMATCHUV > 1 or NMATCHOPT > 1 or<br>    GAL_RE_R > 10 arcsec, where GAL_RE_R is the r-band effective<br>    radius from SersicCatAll. Otherwise the BEST columns are set to<br>    the corresponding SPLIT columns.<br><br>  The flux method used for the BEST columns is recorded in column<br>  BEST_METHOD (CoG or AdvancedMatch).<br><br>  Note that for a COG_FLUX_NUV value to be present *in this catalogue*<br>  it must have S/N >= 2.5 (see above).<br><br>  Also note that there are 250 objects in this catalogue with neither<br>  AdvancedMatch nor CoG entries. These objects were included here only<br>  because they have an entry in GalexSimpleMatch, meaning they have at<br>  least one S/N_NUV >= 2.5 GALEX object from GalexPhot within 4 arcsec. <br>  However, all of these have multiple GALEX objects associated with<br>  them. Hence one should not be tempted to use the UV flux of the<br>  nearest GALEX neighbour as the BEST flux in these cases.<br><br><br>The default value for missing entries in this table is -999.<br><br>",

The present<br>catalogue was created at Caltech using a new version of the GALEX<br>SExtractor-based pipeline (v7).<br><br><br>Some points to note<br>===================<br>Matched apertures: This catalogue is NUV-centric. The S/N of the<br>NUV data is significantly higher than that of the FUV data. We have<br>taken advantage of this by performing source detection only in the<br>NUV, and then carrying out photometry in both bands in apertures<br>defined in the NUV. This has the advantage of improving the<br>reliability and completeness of the FUV detections and providing<br>meaningful UV colors. Please note however that, because source<br>detection is carried out in the NUV, it is possible to obtain negative<br>flux measurements in the FUV. Note also that all catalogue columns<br>without an explicit band reference are derived from the NUV.<br><br>Calibration: The major changes to the GALEX calibration compared to<br>previous versions include updates to the flat fields, flux response<br>trend with time, and a magnitude zero-point correction (0.043 mag<br>fainter in NUV and 0.033 mag fainter in FUV). Further information can<br>be found on the GALEX web page or detailed in <a href=\"http://www.galex.caltech.edu/researcher/gr6_docs/GI_Doc_Ops7.pdf\">this document</a>. Note that<br>due to the time trend and flat field changes one cannot simply apply<br>fixed zero-point corrections to the previus versions of this<br>catalogue.<br><br>Deblending/Shredding: The deblending threshold parameter has been<br>modified to improve the shredding of extended sources. Prior to v7 the<br>pipeline was tuned for point sources. With v7 a better compromise has<br>been reached that reduces the shredding for extended objects less than<br>1 arcmin in diameter.<br><br>Astrometry: The GALEX PSF is ~5 arcsec and the astrometry is only<br>accurate to within ~0.3 arcsec. Analysing the offsets between GALEX<br>and GAMA optical positions we find that the offsets are not systematic<br>and vary from GALEX tile to tile. The principle cause of the<br>astrometric offsets is the limited precision of astrometric catalogues<br>used to derive the plate solutions within the GALEX pipeline.<br><br>Finally we note that the present version of this catalogue was created<br>using the methods and techniques of the GALEX CATalog Team<br>(GCATT). This is a large project underway to produce a definitive<br>GALEX source catalogue.<br><br><br>Artifact flags<br>==============<br>This catalogue contains artifact warning flags for both the NUV and the<br>FUV. These are bitwise-encoded unsigned integers, each of which is the<br>bitwise logical 'or' of some or none of the possible flags listed<br>below. The flags are applied to regions of the image derived entirely<br>from geometry based on knowledge of the detector's orientation and<br>(for some flags) an a priori estimate of the NUV/FUV brightness of<br>known stars. Source brightness criteria for flagging are generous,<br>meaning that false-positives, especially for 'edge' flags, are common.<br>False-negatives are much rarer, but definitely occur with some<br>regularity.<br><br>In practice, the DICHROIC REFLECTION and WINDOW REFLECTION flags are<br>the only flags that one should always select against as these could<br>lead to seriously corrupt fluxes.<br><br><br>Flag name  |   Bit   | Flag value | Meaning                                 <br>           | (LSB=1) | (base 10)  |                                           <br> ----------|---------|--------------------------------------------------------<br> Edge      |    1    |   1        | Detector bevel edge reflection (NUV only) <br> ----------|---------|--------------------------------------------------------<br> Window    |    2    |   2        | Detector window reflection (NUV only)     <br> ----------|---------|--------------------------------------------------------<br> Dichroic  |    3    |   4        | Dichroic reflection                       <br> ----------|---------|--------------------------------------------------------<br> Varpix    |    4    |   8        | Varible pixel based on time slices.<br> ----------|---------|--------------------------------------------------------<br> Brtedge   |    5    |  16        | Bright star near edge of field (NUV only).<br>           |         |            |  Just like #1 but with a higher count rate <br>           |         |            |  requirement (about 10 cps) on the          <br>           |         |            |  generating star.

For each GAMA DR2 object this catalogue lists its nearest<br>neighbour GALEX object provided that the distance between the two is<br>less than 4 arcsec. GAMA DR2 objects without a GALEX nearest neighbour<br>within a distance of 4 arcsec are considered unmatched and are not<br>included in this catalogue. Refer to the table GalexObsInfo for<br>detection limits and to distinguish between GAMA objects that were not<br>detected in the GALEX data and those that were not covered by GALEX.<br><br>To obtain the properties of a given GAMA object's nearest neighbour<br>GALEX object simply join this table with the table GalexPhot on the<br>column GGOID.<br><br>Note that the resolution of the GALEX imaging is ~5 arcsec. This<br>obviously means that a given GALEX detection in GalexPhot may not<br>represent the UV flux of a single GAMA object (defined in the optical)<br>but the joint UV flux of multiple GAMA objects. In these cases it<br>would be incorrect to assign all of the GALEX flux to any single GAMA<br>object. Furthermore, doing so would introduce an environmental bias:<br>GAMA objects with many other close-by objects would be more likely to<br>be associated with a GALEX detection than isolated GAMA objects.<br><br>Hence, as a quality indicator of the match, the number of GALEX<br>objects within 4 arcsec distance to the GAMA objects is listed in<br>column NMATCH4. The column MANY2ONE gives the number of GAMA objects<br>this GALEX object has been matched to. If one of these two columns is<br>larger than 1, this must be considered a multiple match and we<br>recommend the use of the BEST_FLUX_XXX columns in GalexMain instead of<br>the nearest neighbour fluxes.<br><br>Further GALEX objects within a matching radius of 20 arcsec are also<br>listed (in columns GNEIGHBOR_*) to indicate potential multiple<br>matches.<br><br>",

At the most basic level it is a<br>Friends-of-Friends (FoF) group catalogue that has been run on GAMA<br>survey style mocks (put together by Peder Norberg and various<br>collaborators in Durham) to test the quality of the grouping and then<br>run on the real GAMA data in order to extract our best effort<br>groups. The details of the process are discussed extensively in<br><a href=\"http://adsabs.harvard.edu/abs/2011MNRAS.416.2640R\">Robotham et al. 2011 (MNRAS)</a>. <br><br>Note that this release only covers the GAMA G15 survey region, as this<br>is the only region for which DR2 includes data down to the survey<br>limit (r < 19.4 mag).<br><br>This DMU necessarily produces a large number of catalogues and it<br>might seem over-whelming at a glance, but a lot of effort has gone<br>into to simplifying the outputs as much as possible, and limiting the<br>products to the most useful subset of data. The major products are<br>split into the mock groups and the observed GAMA groups. Below we<br>discuss the catalogues contained in the DMU. For most user purposes<br>G3CGal and G3CFoFGroup will be the most useful catalogues.<br><br>For all catalogues the null value is -999 unless stated otherwise.<br><br>The GroupFinding DMU does not have many catalogue dependencies, it<br>only really needs SDSS photometry, RA, DEC, and redshift. The DMUs<br>used to create the GroupFinding DMU are:<br><br>Mocks\t\tv02  (not a GAMA accessible DMU)<br>SpecCat\t        v06<br>InputCat        v11<br><br>Note that the SpecCat and InputCat versions used here are slightly<br>earlier versions than the ones being released in DR2 (v08 and v16,<br>respectively). The difference between these versions is the addition<br>of more re-redshifting data (see the notes of the SpecCat DMU for an<br>explanation of \"re-redshifting\"). That means that for some objects the<br>redshift and redshift quality used in this DMU will be different from<br>those listed by the SpecCat DMU or in TilingCat.<br><br>-----------------------------------------------------------------------<br><br>G3C GAMA group catalogues:<br><br>G3CGal:<br>List of all galaxies that were used for GAMA grouping. The sample<br>covers the G15 survey region only (r < 19.4 mag) and was selected to<br>be between 0.01 < z < 0.5 to avoid LF and distance uncertainties at<br>very low redshift. This catalogue also contains the group references<br>for grouped galaxies.<br><br>G3CFoFGroup:<br>List of FoF group properties. The GroupID references in G3CGal link to<br>this catalogue.<br><br>G3CLink:<br>List of all galaxy-galaxy links found when running the FoF that<br>created G3CFoFGroup. This is useful if the user wished to know which<br>galaxies are linked the most with other galaxies within a group, or to<br>find the most tenuously associated galaxies within a group.<br><br>G3CGalsInPair:<br>A list of all galaxies that are paired with another galaxy within a<br>projected physical separation of 50 kpc/h and a velocity separation of<br>1,000 km/s. Users should be aware that pairs are listed in both<br>gal1-gal2 and gal2-gal1 combinations, so the number of pairs is half<br>the number of links in this catalogue.<br><br>-------------------------------------------------------------------------<br><br>G3C Mock catalogues:<br><br>9 mock catalogues were created in all, where each mock catalogue<br>covers not only the G15 region as is the case for the real data above,<br>but contains a complete analogue of the full GAMA I survey - i.e. 3<br>regions of 12 x 4 deg^2 out to redshift 0.5. Since the 3 regions have<br>the same size and shape this means that the mocks provide a total of 9<br>x 3 = 27 comparison volumes. The mocks are limited to r < 19.4 mag as<br>are the real data. Each catalogue below contains all 9 mock volumes,<br>with a column specifying the relevant volume number.<br><br>G3CMockGal:<br>List of all galaxies that were used for mock grouping. The sample was<br>selected to be between 0.01 < z < 0.5 to be consistent with the cuts<br>made for the real data. This catalogue also contains the group<br>references for grouped galaxies.<br><br>G3CMockFoFGroup:<br>List of FoF group properties for the mocks. The GroupID references in<br>G3CMockGal link to this catalogue.<br><br>G3CMockHaloGroup:<br>List of halo group properties for the mocks. \"Halo group\" refers to<br>the intrinsic group of galaxies that are given in the mock catalogues,<br>so these groups can be considered to be \"the truth\" for comparison<br>purposes. The HaloID references in G3CMockGal link to this<br>catalogue.<br><br>G3CMockLink:<br>List of all mock galaxy-galaxy links found when running the FoF that<br>created G3CMockFoFGroup. This is useful if the user wishes to know<br>which galaxies are linked the most with other galaxies within a group,<br>or to find the most tenuously associated galaxies within a group.<br><br>G3CMockGalsInPair:<br>A list of all mock galaxies that are paired with another mock galaxy<br>within a projected physical separation of 50 kpc/h and a velocity<br>separation of 1,000 km/s.

To obtain a proper total dynamical mass calibration for the groups<br>   the user should read section 4.3 in the accompanying paper<br>   (Robotham et al. 2011). In the present catalogue, MassProxy<br>   is listed with A=1. For Nfof>=5 the suggested best median global<br>   correction for the *user to apply* is A=10.0. This is used in the<br>   MassA column.<br><br>b. To obtain a proper total luminosity calibration for the groups the<br>   user should read section 4.4 in the accompanying paper (Robotham et<br>   al. 2011). In the present catalogue, TotFluxProxy is listed<br>   with B=1. For Nfof>=5 the suggested best median global correction<br>   for the *user to apply* is B=1.04. This is used in the MassB<br>   column.<br><br>c. To obtain a proper total (dynamical) mass calibration for the<br>   groups from their total luminosity the user should calibrate the<br>   luminosity-mass relation independently for the data and the<br>   mocks. This calibration should be done using TotFluxProxy (with the<br>   appropriate B factor) and MassProxy (with the appropriate A<br>   factor). We would generally recommend a median unbiased calibration,<br>   split as function of Nfof and Zfof as has been done in Robotham<br>   et al. (2011) for most group properties.<br><br>d. To avoid any edge effects, only groups with GroupEdge=1 should be<br>   selected. To create a volume limited sample just select the RA and<br>   DEC ranges that don't include any groups that have a GroupEdge less<br>   than 1.<br><br>e. The final four columns (MassA, MassAfunc, LumMassB and LumMassBfunc)<br>   contain the best effort group mass/luminosity scalings. The<br>   functional form using the group redshift and multiplicity has<br>   the \"func\" suffix, and the global median correction does not.<br>",

To obtain a proper total dynamical mass calibration for the groups<br>   the user should read section 4.3 in the accompanying paper<br>   (Robotham et al. 2011). In the present catalogue, MassProxy<br>   is listed with A=1. For Nfof>=5 the suggested best median global<br>   correction for the *user to apply* is A=10.0. This is used in the<br>   MassA column.<br><br>b. To obtain a proper total luminosity calibration for the groups the<br>   user should read section 4.4 in the accompanying paper (Robotham et<br>   al. 2011). In the present catalogue, TotFluxProxy is listed<br>   with B=1. For Nfof>=5 the suggested best median global correction<br>   for the *user to apply* is B=1.04. This is used in the MassB<br>   column.<br><br>c. To obtain a proper total (dynamical) mass calibration for the<br>   groups from their total luminosity the user should calibrate the<br>   luminosity-mass relation independently for the data and the<br>   mocks. This calibration should be done using TotFluxProxy (with the<br>   appropriate B factor) and MassProxy (with the appropriate A<br>   factor). We would generally recommend a median unbiased calibration,<br>   split as function of Nfof and Zfof as has been done in Robotham<br>   et al. (2011) for most group properties.<br><br>d. To avoid any edge effects, only groups with GroupEdge=1 should be<br>   selected. To create a volume limited sample just select the RA and<br>   DEC ranges that don't include any groups that have a GroupEdge less<br>   than 1.<br><br>e. The final four columns (MassA, MassAfunc, LumMassB and LumMassBfunc)<br>   contain the best effort group mass/luminosity scalings. The<br>   functional form using the group redshift and multiplicity has<br>   the \"func\" suffix, and the global median correction does not.<br>",

To obtain a proper total (dynamical) mass calibration for the<br>   groups from their total luminosity the user should calibrate the<br>   luminosity-mass relation independently for the data and the<br>   mocks. This calibration should be done using TotFluxProxy (with the<br>   appropriate B factor) and MassProxy (with the appropriate A<br>   factor). We would generally recommend a median unbiased calibration,<br>   split as function of Nfof and Zfof as has been done in Robotham<br>   et al. (2011) for most group properties.<br><br>d. To avoid any edge effects, only groups with GroupEdge=1 should be<br>   selected. To create a volume limited sample just select the RA and<br>   DEC ranges that don't include any groups that have a GroupEdge less<br>   than 1.<br><br>e. The final four columns (MassA, MassAfunc, LumMassB and LumMassBfunc)<br>   contain the best effort group mass/luminosity scalings. The<br>   functional form using the group redshift and multiplicity has<br>   the \"func\" suffix, and the global median correction does not.<br>",
