VizieR Online Data Catalog: EW and [Fe/H] for 30000 globular cluster RGB stars (Husser+ 2020)

We measured equivalent widths of >30000 red giant branch stars in 25 globular clusters from our large MUSE survey and used mean cluster metallicities to calibrate the CaT-metallicity relation, from which reduced equivalent widths and metallicities were calculated for all stars. Metallicities are given for four different calibrations, based on the classical linear relation with only stars brighter than the HB (1), all RGB stars and a quadratic relation (2), and two calibrations based on absolute magnitude (3) and luminosity (4). All metallicities are derived on the scale defined by Dias et al. (2016A&A...590A...9D). The star IDs are taken from the ACS Survey of Galactic Globular Clusters (Anderson et al., 2008AJ....135.2055A), if they exist in that catalog.
