cds-question@unistra.frglobular-star-clustersobservational-astronomyWe present a photometric investigation on HB, RGB, and MSTO stars in omega Cen = NGC 5139. The center of the cluster was covered with a mosaic of F435W, F625W, and F658N band data collected with HST ACS. The outer reaches were covered with a mosaic of U-, B-, V-, and I-band data collected with the 2.2 m ESO/MPI telescope. The final catalog includes ~1.7 million stars. We identified more than 3200 likely HB stars, the largest sample ever collected in a globular cluster.2007ApJ...663.1021Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/663/1021CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/108/1350 : Omega Cen FUV photometry (Whitney+, 1994)J/AJ/119/1225 : Stroemgren photometry of Omega Cen & NGC 6397 (Hughes+ 2000)J/AJ/119/1824 : Caby photometry of {Omega} Centauri (Rey+, 2000)J/A+A/400/521 : Omega Cen XMM observations (Gendre+, 2003)J/A+A/420/173 : JK photometry of Omega Cen red giants (Sollima+, 2004)J/AJ/127/980 : vby and BVI photometry of Omega Cen giants (Hughes+, 2004)J/MNRAS/357/265 : BVI photometry of omega Cen red giants (Sollima+, 2005)J/ApJ/654/915 : Deep FORS1 BR photometry of omega Cen (Sollima+, 2007)J/AJ/135/1395 : omega Cen Spitzer photometry (Boyer+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/663/1021https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/663/1021http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/663/1021https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/663/1021https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/663/1021http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/663/1021GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/663/1021/table1 (Log of scientific CCD images of Omega Centauri collected with the mosaic camera available at the 2.2m ESO/MPI telescope)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/663/1021/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/663/1021/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/663/1021/table1?GETtext/xml+votable180.050000true201.57875-47.6003060.0055555555555555566/43225 43227https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/663/1021?format=asciiOpticaldefaultJ/ApJ/663/1021/table1Log of scientific CCD images of Omega Centauri collected with the mosaic camera available at the 2.2m ESO/MPI telescoperecnoRecord number assigned by the VizieR team.
