This project was awarded 210 nights over 7 years (2008–2014) and the observations are now completed. This survey builds on, and is augmented by, previous spectroscopic surveys such as the <a href=\"http://www.sdss.org/\">Sloan Digital Sky Survey (SDSS)</a>, the <a href=\"http://www.mso.anu.edu.au/2dFGRS/\">2dF Galaxy Redshift Survey(2dFGRS)</a> and the <a href=\"http://www.eso.org/~jliske/mgc/\">Millennium Galaxy Catalogue (MGC)</a>.</p>",
