cds-question@unistra.fropen-star-clustersinfrared-photometryvisible-astronomybroad-band-photometrypre-main-sequence-starsx-ray-sourcesWe present astrometry and BVI photometry, down to V~22, of the very young open cluster NGC 6530, obtained from observations taken with the Wide Field Imager camera at the MPG/ESO 2.2m Telescope. We have positionally matched our optical catalog with the list of X-ray sources found in a Chandra-ACIS observation, finding a total of 828 common stars, 90% of which are pre-main sequence stars in NGC 6530.2005A&A...430..941Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/430/941CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/430/941https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/430/941http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/430/941https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/430/941https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/430/941http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/430/941GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/430/941/table4 (Cross-identifications of this catalog with the previous works of Walker (1957ApJ...125..636W), Kilambi (1977MNRAS.178..423K) and Sung et al.
