cds-question@unistra.frgiant-starschemical-abundancesglobular-star-clustersWe present an unbiased catalog of calcium abundances for 517 red giants brighter than M_V_~-1 in the chemically inhomogeneous globular cluster omega Centauri. The basic features of the abundance distribution are as follows: (1) few, if any, stars exist on the giant branch of omega Cen with [Ca/H] less than -1.6; (2) there is a well-defined peak in the distribution at [Ca/H]=-1.4, with a long tail stretching up to ~[Ca/H]~-0.3; and (3) the distribution is bimodal with a second smaller peak in the distribution at [Ca/H]=-0.9.1996ApJ...462..241Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/462/241CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/462/241https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/462/241http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/462/241https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/462/241https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/462/241http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/462/241GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/462/241/table3 (Coordinates (J2000) for omega Centauri giants)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/462/241/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/462/241/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/462/241/table3?GETtext/xml+votable180.050000true201.681667-47.4930560.0055555555555555566/43227https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/462/241?format=asciiOpticaldefaultJ/ApJ/462/241/table1Ca II line strength measurements and abundances for omega Centauri giantsrecnoRecord number assigned by the VizieR team.
