AMBRE-UVES

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, Worley et al. 2012, de Laverny et al. 2012, Worley et al. 2016).

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%. More information can be found in the related release documentation.

The catalog of stellar parameters is available via the dedicated Catalog Query Interface or programmatically.

The walk-through on how to produce the Figure above using the programmatic access to the catalogue is illustrated in this forum entry (it requires the installation of the un-official ESOAsg python package).
