The survey region is a long, 35 arcmin wide strip along the equator, covering from 10h 00m to 14h 45m and is fully contained within the regions of both the Two Degree Field Galaxy Redshift Survey (2dFGRS) and the Sloan Digital Sky Survey (SDSS). http://www.eso.org/~jliske/mgc/ Survey Research service-for ivo://wfau.roe.ac.uk/mgc-dsa/ceaApplication MGC: cone search of mgcDetection table http://wfaudata.roe.ac.uk/mgc-dsa/DirectCone?DSACAT=MGC&DSATAB=mgcDetection& 1.500000 2000000 false 150.5 -0.2 0.1 http://wfaudata.roe.ac.uk/mgc-dsa/VOSI/capabilities GET application/xml http://wfaudata.roe.ac.uk/mgc-dsa/VOSI/capabilities GET application/xml http://wfaudata.roe.ac.uk/mgc-dsa/VOSI/availability GET application/xml http://wfaudata.roe.ac.uk/mgc-dsa/VOSI/availability GET application/xml http://wfaudata.roe.ac.uk/mgc-dsa/VOSI/tables GET application/xml http://wfaudata.roe.ac.uk/mgc-dsa/delegations GET application/xml Optical Millennium Galaxy Catalogue The query response table.
