cds-question@unistra.frx-ray-sourcessurveysphotometryWe present the first results from the Calan-Yale Deep Extragalactic Research (CYDER) survey. The main goal of this survey is to study serendipitous X-ray sources detected by Chandra in an intermediate flux range (10^-15^ to 10^-12^ergs/s) that comprises most of the X-ray background. A total of 267 X-ray sources spread over five archived fields were detected.2005ApJ...621..104Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/621/104CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/621/104https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/621/104http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/621/104https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/621/104https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/621/104http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/621/104GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/621/104/table4 (Catalog of X-ray sources in the CYDER fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/621/104/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/621/104/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/621/104/table4?GETtext/xml+votable180.050000true193.26-9.21994440.0055555555555555566/18780 23076 23078 25302 25769 46987https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/621/104?format=asciiX-rayOpticaldefaultJ/ApJ/621/104/table4Catalog of X-ray sources in the CYDER fieldsrecnoRecord number assigned by the VizieR team.
