VizieR Online Data Catalog: Metallicity estimates of M31 globular clusters (Galleti+, 2009)

New empirical relations of [Fe/H] as a function of [MgFe] and Mg_{2 indices are based on the well-studied galactic globular clusters, complemented with theoretical model predictions for -0.2<=[Fe/H]<=+0.5. Lick indices for M31 clusters from various literature sources (225 clusters) and from new observations by our team (71 clusters) have been transformed into the Trager et al. (2000AJ....119.1645T) system, yielding new metallicity estimates for 245 globular clusters of M31.}
