cds-question@unistra.frgalaxiescatalogsredshiftedgalaxy-kinematicsThis paper describes a new catalog that supplements the existing DEEP2 Galaxy Redshift Survey photometric and spectroscopic catalogs with ugriz photometry from two other surveys: the Canada-France-Hawaii Legacy Survey (CFHTLS) and the Sloan Digital Sky Survey (SDSS). Each catalog is cross-matched by position on the sky in order to assign ugriz photometry to objects in the DEEP2 catalogs. We have recalibrated the CFHTLS photometry where it overlaps DEEP2 in order to provide a more uniform data set. We have also used this improved photometry to predict DEEP2 BRI photometry in regions where only poorer measurements were available previously. In addition, we have included improved astrometry tied to SDSS rather than USNO-A2.0 for all DEEP2 objects. In total this catalog contains ~27, 000 objects with full ugriz photometry as well as robust spectroscopic redshift measurements, 64% of which have r > 23. By combining the secure and accurate redshifts of the DEEP2 Galaxy Redshift Survey with ugriz photometry, we have created a catalog that can be used as an excellent testbed for future photo-z studies, including tests of algorithms for surveys such as LSST and DES.2013ApJS..204...21Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/III/268CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://deep.ps.uci.edu/DR4/zcatalog.html : DEEP2-DR4 Home PageII/301 : The DEEP2-DR1 Photometric Catalog (Coil+ 2004)J/ApJ/625/6 : Galaxy groups in the DEEP2 Galaxy Redshift Survey (Gerke+, 2005)J/ApJ/654/115 : DEEP2 Galaxy Redshift Survey: SDSS QSOs (Coil+, 2007)J/ApJS/202/6 : XDEEP2 survey catalog (Goulding+, 2012)J/MNRAS/377/806 : Tully-Fisher relation of DEEP2 galaxies (Chiu+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=III/268https://vizier.iucaa.in/viz-bin/VizieR-2?-source=III/268http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=III/268https://vizier.cds.unistra.fr/viz-bin/votable?-source=III/268https://vizier.iucaa.in/viz-bin/votable?-source=III/268http://vizieridia.saao.ac.za/viz-bin/votable?-source=III/268GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table III/268/deep2all (All observations (is a superset of deep2dr4))https://vizier.cds.unistra.fr/viz-bin/conesearch/III/268/deep2all?https://vizier.iucaa.in/viz-bin/conesearch/III/268/deep2all?http://vizieridia.saao.ac.za/viz-bin/conesearch/III/268/deep2all?GETtext/xml+votable180.050000true213.868751.956450.0055555555555555565/4697 6/9342-9343 9428-9429 11424-11426 11428 17766-17767 17772-17773 18787 18793 187962.258957981392014e-19 4.861318644334812e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/III/268?format=asciidefaultIII/268/deep2allAll observations (is a superset of deep2dr4)recnoRecord number assigned by the VizieR team.
