The initial aim of ATLAS is to survey 4500 deg2 of the Southern Sky at high galactic latitudes to comparable depths to the SDSS in the North. The VST ATLAS will be the first step towards a panoramic digital survey of the Southern Sky in the optical bands. The ATLAS will complement the proposed VISTA Hemisphere Survey in the South. http://astro.dur.ac.uk/Cosmology/vstatlas/ Survey Research service-for ivo://wfau.roe.ac.uk/atlasDR1-dsa/ceaApplication ATLAS_DR1, atlasDetection cone search http://wfaudata.roe.ac.uk/atlasDR1-dsa/DirectCone?DSACAT=ATLAS_DR1&DSATAB=atlasDetection& 1.500000 2000000 false 184.0 -7.5 0.001 http://wfaudata.roe.ac.uk/atlasDR1-dsa/VOSI/capabilities GET application/xml http://wfaudata.roe.ac.uk/atlasDR1-dsa/VOSI/capabilities GET application/xml http://wfaudata.roe.ac.uk/atlasDR1-dsa/VOSI/availability GET application/xml http://wfaudata.roe.ac.uk/atlasDR1-dsa/VOSI/availability GET application/xml http://wfaudata.roe.ac.uk/atlasDR1-dsa/VOSI/tables GET application/xml http://wfaudata.roe.ac.uk/atlasDR1-dsa/delegations GET application/xml ATLAS DR1 The query response table.
