cds-question@unistra.frx-ray-sourcessurveysactive-galactic-nucleiThe Extended Chandra Deep Field-South (ECDFS) survey consists of four Chandra X-Ray Observatory ACIS-I pointings and covers ~1100arcmin^2^ (~0.3{deg}^2^) centered on the original CDF-S field to a depth of approximately 228ks. This is the largest Chandra survey ever conducted at such depth, and only one XMM-Newton survey reaches a lower flux limit in the hard 2.0-8.0keV band. We detect 651 unique sources: 587 using a conservative source-detection threshold and 64 using a lower source-detection threshold. These are presented as two separate catalogs. Of the 651 total sources, 561 are detected in the full 0.5-8.0keV band, 529 in the soft 0.5-2.0keV band, and 335 in the hard 2.0-8.0keV band. For point sources near the aim point, the limiting fluxes are approximately 1.7x10^-16^ and 3.9x10^-16^ergs/cm^2^/s in the 0.5-2.0 and 2.0-8.0keV bands, respectively. Using simulations, we determine the catalog completeness as a function of flux and assess uncertainties in the derived fluxes due to incomplete spectral information. We present the differential and cumulative flux distributions, which are in good agreement with the number counts from previous deep X-ray surveys and with the predictions from an active galactic nucleus (AGN) population synthesis model that can explain the X-ray background. In general, fainter sources have harder X-ray spectra, consistent with the hypothesis that these sources are mainly obscured AGNs.2006AJ....131.2373Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/131/2373CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/126/539 : The Chandra Deep Fields North and South (Alexander+, 2003)J/ApJS/161/21 : Extended Chandra Deep Field-South survey (Lehmer+, 2005)J/ApJ/595/685 : HST imaging in Chandra Deep Field-South (Grogin+, 2003)J/ApJS/139/369 : Chandra Deep Field South. 1 Ms catalog (Giacconi+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/131/2373https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/131/2373http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/131/2373https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/131/2373https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/131/2373http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/131/2373GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/131/2373/cat (Catalog of X-ray sources in the ECDFS field (tables 4 and 5 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/131/2373/cat?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/131/2373/cat?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/131/2373/cat?GETtext/xml+votable180.050000true53.4199167-27.60202780.005555555555555556Cone search capability for table J/AJ/131/2373/table6 (Catalog of collapsed Wavdetect X-ray sources in the ECDFS Survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/131/2373/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/131/2373/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/131/2373/table6?GETtext/xml+votable180.050000true53.0369583-27.98613890.0055555555555555566/35934 35935 35957https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/131/2373?format=asciiX-raydefaultJ/AJ/131/2373/catCatalog of X-ray sources in the ECDFS field (tables 4 and 5 of the paper)NotesNotes (5)meta.notecharrecnoRecord number assigned by the VizieR team.
