Malavolta, Luca; Sneden, Chris; Piotto, G; Milone, Antonino; Bedin, L R; Nascimbeni, Valerio


We report new metallicities for stars of Galactic globular cluster M4 using the largest number of stars ever observed at high spectral resolution in any cluster. We analyzed 7250 spectra for 2771 cluster stars gathered with the Very Large Telescope (VLT)
