cds-question@unistra.fropen-star-clustersearly-type-starspre-main-sequence-starsx-ray-sourcesWe report here results from a Chandra ACIS observation of the stellar populations in and around the M17 HII region. The field reveals 886 sources with observed X-ray luminosities (uncorrected for absorption) between ~29.3ergs/s<logL_X_<32.8ergs/s, 771 of which have stellar counterparts in infrared images.2007ApJS..169..353Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/169/353CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/169/353https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/169/353http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/169/353https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/169/353https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/169/353http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/169/353GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/169/353/Xsources (Primary and tentative sources (tables 1 and 2 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/169/353/Xsources?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/169/353/Xsources?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/169/353/Xsources?GETtext/xml+votable180.050000true274.9898333-16.201250.0055555555555555566/29116 291182.483060040379131e-20 1.7798557115773645e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/169/353?format=asciiX-raydefaultJ/ApJS/169/353/XsourcesPrimary and tentative sources (tables 1 and 2 of the paper)l_logPLimit flag on logPmeta.code.errorcharrecnoRecord number assigned by the VizieR team.
