cds-question@unistra.frquasarsactive-galactic-nucleix-ray-sourcesWe present the X-ray source catalog for the 479ks Chandra exposure of the SDSS J1030+0524 field, that is centered on a region that shows the best evidence to date of an overdensity around a z>6 quasar, and also includes a galaxy overdensity around a Comptonthick Fanaro-Riley type II (FRII) radio galaxy at z=1.7. Using wavdetect for initial source detection and ACIS Extract for source photometry and significance assessment, we create preliminary catalogs of sources that are detected in the full (0.5-7.0keV), soft (0.5-2.0keV), and hard (2-7keV) bands, respectively. We produce X-ray simulations that mirror our Chandra observation to filter our preliminary catalogs and get a completeness level of > 91% and a reliability level of 95% in each band. The catalogs in the three bands are then matched into a final main catalog of 256 unique sources. Among them, 244, 193, and 208 are detected in the full, soft, and hard bands, respectively. The Chandra observation covers a total area of 335 arcmin2, and reaches flux limits over the central few square arcmins of ~3x10^-16^, 6x10^-17^, and 2x10^-16^erg/cm2/s in the full, soft, and hard bands, respectively This makes J1030 field the fifth deepest extragalactic X-ray survey to date. The field is part of the Multiwavelength Survey by Yale-Chile (MUSYC), and is also covered by optical imaging data from the Large Binocular Camera (LBC) at the Large Binocular Telescope (LBT), near-IR imaging data from the Canada France Hawaii Telescope WIRCam (CFHT/WIRCam), and Spitzer IRAC. Thanks to its dense multi-wavelength coverage, J1030 represents a legacy field for the study of large-scale structures around distant accreting supermassive black holes. Using a likelihood ratio analysis, we associate multi-band (r, z, J, and 4.5um) counterparts for 252 (98.4%) of the 256 Chandra sources, with an estimated reliability of 95%. Finally, we compute the cumulative number of sources in each X-ray band, finding that they are in general agreement with the results from the Chandra Deep Fields.2020A&A...637A..52Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/637/A52CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/637/A52https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/637/A52http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/637/A52https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/637/A52https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/637/A52http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/637/A52GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/637/A52/catalog (Chandra source catalog (table 4))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/637/A52/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/637/A52/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/637/A52/catalog?GETtext/xml+votable180.050000true157.6045.31927780.0055555555555555566/274404.414320678087048e-20 4.414320678087048e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/637/A52?format=asciiX-raydefaultJ/A+A/637/A52/catalogChandra source catalog (table 4)recnoRecord number assigned by the VizieR team.
