cds-question@unistra.fractive-galactic-nucleix-ray-sourcesThe XBootes Survey is a 5ks Chandra survey of the Bootes Field of the NOAO Deep Wide-Field Survey (NDWFS). This survey is unique in that it is the largest (9.3{deg}^2^) contiguous region imaged in X-ray with complementary deep optical and near-infrared (near-IR) observations. We present a catalog of the optical counterparts to the 3213 X-ray point sources detected in the XBootes survey. Using a Bayesian identification scheme, we successfully identified optical counterparts for 98% of the X-ray point sources.2006ApJ...641..140Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/641/140CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://www.noao.edu/noao/noaodeep/ : NOAO Deep Wide-Field SurveyJ/ApJS/161/9 : X-ray survey of the NDWFS Bootes field (Kenter+, 2005)J/AJ/130/923 : Faint radio sources in the NOAO Bootes field (Wrobel+, 2005)J/AJ/127/213 : LALA Bootes field X-ray source catalog (Wang+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/641/140https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/641/140http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/641/140https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/641/140https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/641/140http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/641/140GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/641/140/table2 (Table showing the optical characteristic of the matched optical/X-ray catalog for the Chandra sources in the Bootes field of the NDWFS.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/641/140/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/641/140/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/641/140/table2?GETtext/xml+votable180.050000true216.137583334.47215280.0055555555555555565/2286 2287 2628 2629 6/9135 9194 10501 10521 10524 10560https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/641/140?format=asciiX-raydefaultJ/ApJ/641/140/bwfilterTransmission curv of the B_W_ filterrecnoRecord number assigned by the VizieR team.
