cds-question@unistra.frmagellanic-cloudsgiant-starsradial-velocitychemical-abundancesWe report metallicities and radial velocities derived from spectra at the near-infrared calcium triplet for 373 red giants in a 200arcmin^2^ area at the optical center of the LMC bar. These are the first spectroscopic abundance measurements of intermediate-age and old field stars in the high surface brightness heart of the LMC. The metallicity distribution is sharply peaked at the median value [Fe/H]=-0.40, with a small tail of stars extending down to [Fe/H]<=-2.1; 10% of the red giants are observed to have [Fe/H]<=-0.7.2005AJ....129.1465Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/129/1465CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/AJ/120/1808 : Stroemgren photometry in LMC disk (Cole+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/129/1465https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/129/1465http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/129/1465https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/129/1465https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/129/1465http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/129/1465GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/129/1465/stars (Read giants in the bar field (tables 2 and 3 of paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/129/1465/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/129/1465/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/129/1465/stars?GETtext/xml+votable180.050000true80.7824306-69.83497310.0055555555555555566/33096-330972.367228618189496e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/129/1465?format=asciidefaultJ/AJ/129/1465/starsRead giants in the bar field (tables 2 and 3 of paper)SimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
