cds-question@unistra.frx-ray-sourcesactive-galactic-nucleisurveysWe present results from a Chandra survey of the 9deg^2^ Bootes field of the NOAO Deep Wide-Field Survey (NDWFS). This XBootes survey consists of 126 separate contiguous ACIS-I observations each of approximately 5000s in duration. These unique Chandra observations allow us to search for large-scale structure and to calculate X-ray source statistics over a wide, contiguous field of view with arcsecond angular resolution and uniform coverage. The full 0.5-7keV band n>=4 count list has 3293 point sources. In addition to the point sources, 43 extended sources have been detected, consistent with the depth of these observations and the number counts of clusters. We present here the X-ray catalog for the XBootes survey, including source positions, X-ray fluxes, hardness ratios, and their uncertainties.2005ApJS..161....9Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/161/9CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/641/140 : Optical counterparts in the NDWFS Bootes field (Brand+, 2006)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/ApJS/161/9https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/161/9http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/161/9https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/161/9https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/161/9http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/161/9GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/161/9/table1 (Properties of extended sources in the XBootes Survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/161/9/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/161/9/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/161/9/table1?GETtext/xml+votable180.050000true216.366083332.94623890.005555555555555556Cone search capability for table J/ApJS/161/9/table3 (Properties of point sources in the XBootes survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/161/9/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/161/9/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/161/9/table3?GETtext/xml+votable180.050000true216.0857533.65614720.0055555555555555565/2286 2287 2628 2629 6/9135 9194 10501 10521 10524 10560https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/161/9?format=asciiX-raydefaultJ/ApJS/161/9/table1Properties of extended sources in the XBootes Surveye_SctsError on Sctsctstat.errorfloatrecnoRecord number assigned by the VizieR team.
