cds-question@unistra.frglobular-star-clustersradial-velocityThis paper presents a catalog of the mean radial velocities of 471 giant stars in the galactic globular cluster Omega Cen, the large majority of which are confirmed as cluster members. The typical uncertainty in the mean velocities is less than 1kms; a variability indicator and notes on chemical peculiarities are provided. In extension of earlier dynamical analyses of Omega Cen, based on part of the data presented here (Meylan & Mayor 1986A&A...166..122M; Meylan 1987A&A...184..144M; Meylan et al. 1995A&A...303..761M), a companion paper (Merritt et al. 1997AJ....114.1074M) rediscusses the subject, based on the full data set and a new theoretical approach, using nonparametric techniques.1997AJ....114.1087Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/114/1087CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/114/1087https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/114/1087http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/114/1087https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/114/1087https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/114/1087http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/114/1087GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/114/1087/table1Catalog of mean radial velocities for the {omega} Centauri program starsrecnoRecord number assigned by the VizieR team.
