cds-question@unistra.frx-ray-sourcesspectroscopyredshiftedWe present the redshift catalogs for the X-ray sources detected in the Chandra Deep Field-North (CDF-N), the Chandra Large Area Synoptic X-ray Survey (CLASXS), and the Chandra Lockman Area North Survey (CLANS). The catalogs for the CDF-N and CLASXS fields include redshifts from previous work, while the redshifts for the CLANS field are all new. For fluxes above 10^-14^ergs/cm^2^/s (2-8keV) we have redshifts for 76% of the sources. We extend the redshift information for the full sample using photometric redshifts. The goal of the OPTX Project is to use these three surveys, which are among the most spectroscopically complete surveys to date, to analyze the effect of spectral type on the shape and evolution of the X-ray luminosity functions and to compare the optical spectral types with the X-ray spectral properties. We also present the CLANS X-ray catalog. The nine ACIS-I fields cover a solid angle of ~0.6deg^2^ and reach fluxes of 7x10^-16^ergs/cm^2^/s (0.5-2keV) and 3.5x10^-15^ergs/cm^2^/s (2-8keV). We find a total of 761 X-ray point sources. In addition, we present the optical and infrared photometric catalog for the CLANS X-ray sources, as well as updated optical and infrared photometric catalogs for the X-ray sources in the CLASXS and CDF-N fields.2008ApJS..179....1Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/179/1CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-)J/ApJ/653/1004 : Galaxies at 1.4<~z<~3.0 in GOODS-North Field (Reddy+, 2006)J/ApJ/622/772 : Redshift survey of submillimeter galaxies (Chapman+, 2005)J/AJ/128/1483 : Optical properties of the CLASXS X-ray sample (Steffen+, 2004)J/AJ/128/1501 : CLASXS: X-ray catalog (Yang+, 2004)J/AJ/126/632 : UBVRIz'HK' photometry of 2Ms CDFN X-ray sources (Barger+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/179/1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/179/1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/179/1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/179/1https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/179/1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/179/1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/179/1/clans (CLANS Catalog: X-ray source)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/179/1/clans?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/179/1/clans?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/179/1/clans?GETtext/xml+votable180.050000true160.5884659.251570.005555555555555556Cone search capability for table J/ApJS/179/1/table12 (CLASXS Optical/IR counterparts catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/179/1/table12?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/179/1/table12?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/179/1/table12?GETtext/xml+votable180.050000true157.73157.5560.005555555555555556Cone search capability for table J/ApJS/179/1/table13 (CDF-N Optical/IR counterparts catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/179/1/table13?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/179/1/table13?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/179/1/table13?GETtext/xml+votable180.050000true188.81362.2350.0055555555555555566/6073 6075 6077 6079 11230 11252https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/179/1?format=asciiX-rayOpticaldefaultJ/ApJS/179/1/clansCLANS Catalog: X-ray sourcerecnoRecord number assigned by the VizieR team.
