cds-question@unistra.frglobular-star-clustersgiant-starsvisible-astronomymedium-band-photometryWe have obtained photometric observations in a 182arcmin^2 area, 25' to the north of the center of the globular cluster {omega} Centauri. The Stroemgren vby and broadband BI filters were used to obtain measurements for some 2500 stars. Preliminary examinations of parts of the data have been presented previously (Hughes & Wallerstein, 2000, Cat. <J/AJ/119/1225>; Hughes, Wallerstein, & van Leeuwen, 2002, in ASP Conf. Ser. 265, 73). Here we present the complete data set, study the giant branches, and use the B-I color index as a tool for assessing the ages of the populations within {omega} Cen.2004AJ....127..980Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/127/980CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/127/958 : CCD BV photometry on Omega Cen (Rey+, 2004)J/AJ/119/1225 : Stroemgren photometry of Omega Cen & NGC 6397 (Hughes+, 2000)J/A+AS/115/297 : BVRI photometry of Central Field of Omega Cen (Lynga+, 1996)J/AJ/108/1350 : Omega Cen FUV photometry (Whitney+, 1994)J/MNRAS/250/314 : CCD photometry of omega Cen (Noble+ 1991)J/PASP/106/828 : BVRI photometry of Omega Cen (Walker 1994)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/127/980https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/127/980http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/127/980https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/127/980https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/127/980http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/127/980GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/127/980/position (Positions, from van Leeuwen et al., 2000, Cat. <J/A+A/360/472>)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/127/980/position?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/127/980/position?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/127/980/position?GETtext/xml+votable180.050000true201.60222-47.153090.005555555555555556Cone search capability for table J/AJ/127/980/table2 (Multiwavelength Data on {omega} Centauri (Northern Field))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/127/980/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/127/980/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/127/980/table2?GETtext/xml+votable180.050000true201.7211583-47.13971750.0055555555555555566/43227https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/127/980?format=asciiOpticaldefaultJ/AJ/127/980/positionPositions, from van Leeuwen et al., 2000, Cat. <J/A+A/360/472>recnoRecord number assigned by the VizieR team.
