cds-question@unistra.frsurveysx-ray-sourcesWe present the results of a 200-ks Chandra observation of part of the Groth Strip region, using the ACIS-I instrument. We present a relatively simple method for the detection of point sources and calculation of limiting sensitivities, which we argue is at least as sensitive and more self-consistent than previous methods presented in the literature. A total of 158 distinct X-ray sources are included in our point-source catalogue in the ACIS-I area. The number counts show a relative dearth of X-ray sources in this region.2005MNRAS.356..568Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/356/568CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 2002-)J/MNRAS/351/1290 : ELAIS: final band-merged catalogue (Rowan-Robinson+, 2004)J/ApJ/554/742 : Chandra Deep Survey of the HDF-N (Hornschemeier+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/356/568https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/356/568http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/356/568https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/356/568https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/356/568http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/356/568GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/356/568/Xsrc (Chandra GWS sources, plus additional sources in ELAIS-N1 and HDF-N)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/356/568/Xsrc?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/356/568/Xsrc?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/356/568/Xsrc?GETtext/xml+votable180.050000true214.17541752.5283330.0055555555555555566/10153 11230 11252 11424-11425https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/356/568?format=asciiX-raydefaultJ/MNRAS/356/568/XsrcChandra GWS sources, plus additional sources in ELAIS-N1 and HDF-Nl_FBLimit flag on FBmeta.code.errorcharrecnoRecord number assigned by the VizieR team.
