cds-question@unistra.frx-ray-sourcesinfrared-photometrysurveysWe present a catalog of 5184 candidate infrared counterparts to X-ray sources detected toward the Galactic center. The X-ray sample contains 9017 point sources detected in this region by the Chandra X-ray Observatory during the past decade, including data from a recent deep survey of the central 2{deg}x0.8{deg} of the Galactic plane. A total of 6760 of these sources have hard X-ray colors, and the majority of them lie near the Galactic center, while most of the remaining 2257 soft X-ray sources lie in the foreground. We cross-correlated the X-ray source positions with the 2MASS and SIRIUS near-infrared catalogs, which collectively contain stars with a 10{sigma} limiting flux of Ks<=15.6mag. For each of the infrared matches to X-ray sources in our catalog we derived the probability that the association is real, based on the source properties and the results of the cross-correlation analysis.2009ApJ...703...30Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/703/30CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/ApJS/181/110 : Galactic center X-ray sources (Muno+, 2009)J/ApJ/685/958 : Spitzer and Chandra sources in galactic center (Arendt+ 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/703/30https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/703/30http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/703/30https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/703/30https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/703/30http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/703/30GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/703/30/table3 (Candidate infrared counterparts to X-ray sources toward the Galactic Center)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/703/30/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/703/30/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/703/30/table3?GETtext/xml+votable180.050000true266.23814-28.961020.0055555555555555566/28825 28827 28828 28830 288317.952274030004205e-20 1.7798557115773645e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/703/30?format=asciiX-rayInfrareddefaultJ/ApJ/703/30/table3Candidate infrared counterparts to X-ray sources toward the Galactic CenterrecnoRecord number assigned by the VizieR team.
