cds-question@unistra.fropen-star-clustersphotometryWe present the results of a 0.86 square degree CCD photometric survey of the open cluster NGC 2516, which has an age of about 150Myr and may have a much lower metallicity than the similarly-aged Pleiades. Our BVI_c_ survey of cluster members is complete to V~20 and is used to select a preliminary catalogue of 1254 low mass (0.<M<2.0M_{sun}_) cluster candidates, of which about 70-80 percent are expected to be genuine. After applying corrections for contamination by non-members and adding data for higher mass stars from the literature, we investigate the cluster binarity, luminosity and mass function, mass segregation and total mass. We find a binary fraction of 26+/-5%, for A to M-type systems with mass ratios between 0.6 and 1, which is very similar to the Pleiades.2001A&A...375..863Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/375/863CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/375/863https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/375/863http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/375/863https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/375/863https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/375/863http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/375/863GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/375/863/table3 (The photometric catalogue for NGC 2516)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/375/863/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/375/863/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/375/863/table3?GETtext/xml+votable180.050000true118.53527917-61.013988890.0055555555555555565/9398 6/37586-37587https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/375/863?format=asciiOpticaldefaultJ/A+A/375/863/table3The photometric catalogue for NGC 2516recnoRecord number assigned by the VizieR team.
