cds-question@unistra.frinfrared-photometryradial-velocityspectroscopyWe have obtained spectra of 85 giants selected from IR photometry in the fields of several very reddened galactic clusters. Radial velocities are measured to check membership. We measure the strength of several Fe and Mg spectral feature s, presenting a new calibration of metallicity based on the location of the giants in the Mg+Fe5270+Fe5335 vs (J-K)_0_ diagram. Using this calibration we compute accurate mean metallicities for the clusters studied. Reddening values which better fit the spectroscopic and photometric data are also derived. Pal 6 turns out to be the most metal rich cluster of our sample, with [Fe/H]=0.2+/-0.3.1995A&A...303..468Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/303/468CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/303/468https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/303/468http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/303/468https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/303/468https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/303/468http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/303/468GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapInfrareddefaultJ/A+A/303/468/table3Colors, velocities and spectral indicesrecnoRecord number assigned by the VizieR team.
