Second Data Release from the MATISSE/OCA-ESO Project (AMBRE)
The AMBRE collaboration between the Observatoire de la Côte d'Azur (OCA, Nice) and ESO has the goal to analyse the wealth of stellar spectroscopic data in the ESO science archive using the MATISSE parametrisation algorithm to derive stellar atmospheric parameters (Recio-Blanco et al., 2006, MNRAS 370, 141, Worley et al. 2012, A&A 542A, 48, de Laverny et al. 2012, A&A 544A, 126).
This data release provides stellar radial velocity, effective temperature, surface gravity, mean metallicity and enrichment in alpha-elements for about 6600 stellar objects observed between March 2000 and November 2010 using the VLT/UVES spectrograph. 51897 stellar spectra were analysed in total, resulting in the complete parameter set for about 20%.
