Stripe 82X is a 31.3 X-ray survey with Chandra and XMM-Newton observations overlapping the legacy Sloan Digital Sky Survey Stripe 82 field, which has a rich investment of multiwavelength coverage from the ultraviolet to the radio. The wide-area nature of this survey presents new challenges for photometric redshifts for AGNs compared to previous work on narrow-deep fields because it probes different populations of objects that need to be identified and represented in the library of templates. Here we present an updated X-ray plus multiwavelength matched catalog, including Spitzer counterparts, and estimated photometric redshifts for 5961 (96% of a total of 6181) X-ray sources that have a normalized median absolute deviation, {sigma}_nmad_=0.06, and an outlier fraction, {eta}=13.7%. The populations found in this survey and the template libraries used for photometric redshifts provide important guiding principles for upcoming large-area surveys such as eROSITA and 3XMM (in X-ray) and the Large Synoptic Survey Telescope (optical).2017ApJ...850...66Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/850/66CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/219/39 : QSOs selection from SDSS and WISE (Richards+, 2015)J/ApJ/817/172 : X-ray Observations of Stripe 82 (LaMassa+, 2016)J/MNRAS/456/1359 : IAC Stripe 82 Legacy Project: Photometry (Fliri+, 2016)J/ApJS/225/1 : SpIES: the Spitzer IRAC Equatorial Survey (Timlin+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/850/66https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/850/66http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/850/66https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/850/66https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/850/66http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/850/66GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/850/66/table13 (Catalog (final version, 21/08/2019))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/850/66/table13?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/850/66/table13?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/850/66/table13?GETtext/xml+votable180.050000true333.4755556-0.34805220.0055555555555555565/4438 4457 4458 4500 4501 4502 4505 4522 4697 5802 6/17406 17407 17662 17663 17742 17743 17745 17748 17749 17758 17761 17763 17764 17766 17767 17769 17772 17773 17780 17806 17807 17816 17817 17819 17826 17827 17836 17840 17841 17842 17991 17997 17999 18012 18019 18024 18025 18028 18032 18065 18069 18071 18073 18074 18076 18078 18085 18086 18092 18096 18112 18114 18176 18766 18772 18773 18774 18777 18778 18779 18780 18782 18785 18787 18793 18794 18795 18796 18800 18865 18881 19023 19027 19030 19032 19033 19035 19036 19038 19045 19056 19058 19091 19097 19099 19108 19110 19456 19457 19458 23102 23145 23148 23150 23182 23183 23190 23191 23192 23196 23197 23234 30029 30031 36861 368632.040811542443644e-19 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/850/66?format=asciiX-rayOpticalInfraredUVdefaultJ/ApJ/850/66/table13Catalog (final version, 21/08/2019)zsp?
