Search: Cone

Search for sources within a specified radius of a sky position

Cone Search

Conduct a cone search of a specified radius around a set of coordinates, returning up to 5000 records of astronomical sources from the Data Central Archive.

Right Ascension. Format is as: 10.2345d (degrees with 'd' abbreviation for degrees) or 1:2:30.43d (sexagesimal degrees). See the docs for other supported formats.

Declination. Format is as: 0.93489316d (degrees with 'd' abbreviation for degrees) or -0d16m17.6s (degree arcmin arcsec). See the docs for other supported formats.

Specify the frame of the coordinates

Valid values are b1950 and j2000 (default)

Minimum value = 5", maximum value = 3600". Warning values above 300" will take some time.

Using the Cone Search

The cone search service supports a wide variety of input formats for coordinates:

  • degrees (10.2345d)
  • sexagesimal degrees (1:2:30.43d)
  • sexagesimal hours (1 2 0 hours)
  • degree, arcmin, and arcsec (1d2m3.4s)
  • hour, minute, second (-1h2m3s)

If you are unsure of the position of a source, use the name resolver to find its coordinates. If you know the survey-id of the object you're interested in, try the AstroObject search.

Don't forget to include the string format identifier, e.g., for coordinates in degrees, append 'd':

See a list of astropy's angle documentation for a list of all possible formats.

The cone search uses the following tables to query positions for each survey. Find more information on each in the schema browser.
