cds-question@unistra.frglobular-star-clustersgiant-starsline-intensitiesradial-velocityWell determined radial velocities and abundances are essential for analyzing the properties of the Globular Cluster system of the Milky Way. However more than 50% of these clusters have no spectroscopic measure of their metallicity. In this context, this work provides new radial velocities and abundances for twenty Milky Way globular clusters which lack or have poorly known values for these quantities. The radial velocities and abundances are derived from spectra obtained at the CaII triplet using the FORS2 imager and spectrograph at the VLT, calibrated with spectra of red giants in a number of clusters with well determined abundances. For about half of the clusters in our sample we present signifiant revisions of the existing velocities or abundances, or both.2012A&A...540A..27Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/540/A27CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/705/1481 : Spectroscopy of stars in 6 globular clusters (Da Costa+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/540/A27https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/540/A27http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/540/A27https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/540/A27https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/540/A27http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/540/A27GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/540/A27/clusters (Cluster list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/540/A27/clusters?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/540/A27/clusters?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/540/A27/clusters?GETtext/xml+votable180.050000true154.4034167-46.41247220.005555555555555556Cone search capability for table J/A+A/540/A27/stars (Combined table from original tables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/540/A27/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/540/A27/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/540/A27/stars?GETtext/xml+votable180.050000true154.45472-46.416050.0055555555555555566/12405 12531 12943 28705 28768-28769 28778 28838 28882 28972-28973 29233 29267 29294 29637 31019 37294 38465 39954 42076 42152 42361 42761 42789 42800 42955 43193 44086 47916 48035https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/540/A27?format=asciiOpticaldefaultJ/A+A/540/A27/clustersCluster listrecnoRecord number assigned by the VizieR team.
