cds-question@unistra.fropen-star-clustersx-ray-sourcesinfrared-photometryvisible-astronomybroad-band-photometryWe present a comprehensive study of the Chandra X-ray observations of the young open cluster NGC 2516. We have analyzed eight individual Chandra observations. We have combined the data to achieve the greatest sensitivity, reaching down to log f_X_=-14.56(erg/s/cm^2^), or logLX=28.69(erg/s) at the distance of NGC 2516. Out of 284 X-ray sources detected, 155 are identified with photometric cluster members, with very little ambiguity.2003ApJ...588.1009Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/588/1009CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/123/290 : UBVI CCD photometry of NGC 2516 (Sung+, 2002)J/A+A/312/818 : NGC 2516 X-ray sources (Dachs+, 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/588/1009https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/588/1009http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/588/1009https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/588/1009https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/588/1009http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/588/1009GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/588/1009/table4 (NGC 2516 X-ray source optical identifications)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/588/1009/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/588/1009/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/588/1009/table4?GETtext/xml+votable180.050000true119.09375-60.86172220.005555555555555556Cone search capability for table J/ApJ/588/1009/table6 (Upper limits to X-ray luminosities for undetected NGC 2516 members)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/588/1009/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/588/1009/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/588/1009/table6?GETtext/xml+votable180.050000true118.75429167-60.524541670.0055555555555555566/37592 37593 37594https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/588/1009?format=asciiX-rayOpticalInfrareddefaultJ/ApJ/588/1009/table4NGC 2516 X-ray source optical identificationsrecnoRecord number assigned by the VizieR team.
