cds-question@unistra.frsurveysgalaxiesinfrared-sourcesphotometryredshiftedWe have revised the Spitzer Wide-Area Infrared Extragalactic survey (SWIRE) Photometric Redshift Catalogue to take account of new optical photometry in several of the SWIRE areas, and incorporating Two Micron All Sky Survey (2MASS) and UKIRT Infrared Deep Sky Survey (UKIDSS) near-infrared data. Aperture matching is an important issue for combining near-infrared and optical data, and we have explored a number of methods of doing this. The increased number of photometric bands available for the redshift solution results in improvements both in the rms error and, especially, in the outlier rate. We have also found that incorporating the dust torus emission into the quasi-stellar object (QSO) templates improves the performance for QSO redshift estimation. Our revised redshift catalogue contains over 1 million extragalactic objects, of which 26 288 are QSOs.2013MNRAS.428.1958Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/II/326CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/255 : SWIRE ELAIS N1 Source Catalogs (Surace+, 2004)III/250 : The VIMOS VLT deep survey (VVDS-DEEP) (Le Fevre+ 2005)J/MNRAS/351/1290 : ELAIS: final band-merged catalogue (Rowan-Robinson+, 2004)J/AJ/128/1483 : Optical properties of CLASXS X-ray sample (Steffen+, 2004)J/AJ/129/1198 : SDSS quasars in SWIRE ELAIS N1 field (Hatziminaoglou+, 2005)J/AJ/129/2074 : Faint Chandra sources in SWIRE (Franceschini+, 2005)J/A+A/467/565 : z=1-3 ULIRGs from the Spitzer SWIRE survey (Berta+, 2007)J/A+A/476/151 : SWIRE ELAIS-S1 IR-peak galaxy IR fluxes (Berta+, 2007)J/MNRAS/379/1343 : UKIDSS massive supercluster infrared study (Swinbank+, 2007)J/MNRAS/386/1252 : SWIRE/SDSS quasars (Hatziminaoglou+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=II/326https://vizier.iucaa.in/viz-bin/VizieR-2?-source=II/326http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=II/326https://vizier.cds.unistra.fr/viz-bin/votable?-source=II/326https://vizier.iucaa.in/viz-bin/votable?-source=II/326http://vizieridia.saao.ac.za/viz-bin/votable?-source=II/326GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table II/326/zcatrev (Revised SWIRE photometric redshift catalogues)https://vizier.cds.unistra.fr/viz-bin/conesearch/II/326/zcatrev?https://vizier.iucaa.in/viz-bin/conesearch/II/326/zcatrev?http://vizieridia.saao.ac.za/viz-bin/conesearch/II/326/zcatrev?GETtext/xml+votable180.050000true243.059951952.94160110.0055555555555555565/1517 1519 2410 2538 2539 2880 4422 8983 6/6047 6067 6073 6075 6090 6112 6114 6120 7444 7445 9463 9469 9471 9633 9634 9635 9636 9638 9644 9983 10146 10147 10150 10151 11349 11524 11526 17671 17677 17679 17681 17682 17683 17684 17686 17692 17694 17712 17713 17714 35387 35388 35390 35473 35476 35926 35927 35929 35931 35953 35956 35957 36104 361061.5891567668987121e-22 5.934602767263733e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/II/326?format=asciiInfrareddefaultII/326/zcatrevRevised SWIRE photometric redshift cataloguese_S24? rms uncertainty on S24uJystat.errordoublenullableUmag?
