Description Stellar radial velocity, atmospheric parameters (effective temperature, surface gravity, mean metallicity [M/H]) and enrichment in alpha-elements ([alpha/Fe]) resulting from the automatic analysis of the ESO spectral data archives of the FEROS, UVES, HARPS and FLAMES instruments with the MATISSE algorithm. This first release concerns the FEROS data collected from 2005, October to 2009, December.
