cds-question@unistra.fropen-star-clustersx-ray-sourcesWe report a deep X-ray survey of the young (~140Myr), rich open cluster NGC 2516 obtained with the EPIC camera on board the XMM-Newton satellite. By combining data from six observations, a high sensitivity, greater than a factor of 5 with respect to recent Chandra observations, has been achieved. Kaplan-Meier estimators of the cumulative X-ray luminosity distribution are built, statistically corrected for non members contaminants and compared to those of the nearly coeval Pleiades. The EPIC spectra of the X-ray brightest stars are fitted using optically thin model plasma with one or two thermal components. We detected 431 X-ray sources and 234 of them have as optical counterparts cluster stars spanning the entire NGC 2516 Main Sequence.2006A&A...450..993Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/450/993CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/312/818 : NGC 2516 X-ray sources (Dachs+, 1996)J/A+A/375/863 : Photometry in NGC 2516 (Jeffries+, 2001)J/AJ/123/290 : UBVI CCD photometry of NGC 2516 (Sung+, 2002)J/ApJ/588/1009 : Chandra X-ray observations of NGC 2516 (Damiani+, 2003)J/ApJ/606/466 : X-ray variability in NGC 2516 (Wolk+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/450/993https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/450/993http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/450/993https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/450/993https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/450/993http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/450/993GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/450/993/tablea1 (List of detected X-ray sources in the combined images of the XMM-Newton EPIC camera.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/450/993/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/450/993/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/450/993/tablea1?GETtext/xml+votable180.050000true119.3359583-61.07201940.005555555555555556Cone search capability for table J/A+A/450/993/tablec1 (X-ray undetected stars of NGC 2516)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/450/993/tablec1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/450/993/tablec1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/450/993/tablec1?GETtext/xml+votable180.050000true119.03675-60.826841670.0055555555555555566/37592-37593https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/450/993?format=asciiX-raydefaultJ/A+A/450/993/tablea1List of detected X-ray sources in the combined images of the XMM-Newton EPIC camera.OffaxisOffaxis distancearcminphys.veloc.ang;instr.offsetfloatUn[U] U: unidentified sourcemeta.codecharrecnoRecord number assigned by the VizieR team.
