Gaia-ESO Survey overview

New reduced data products resulting from the Gaia-ESO Public Spectroscopic Survey are now available via the Phase 3 dedicated query interface at the Science Archive Facility.

The present data release includes wavelength calibrated 1-dimensional spectra of point-like sources obtained with FLAMES from 31 December 2011 to 31 December 2013 under ESO program ID 188.B-3002, as well as a catalogue containing photometry and derived quantities (radial velocities, astrophysical parameters, lithium line strength, Hα emission) for a fraction of the stars for which spectra are delivered.

The total number of submitted data files in the Gaia ESO survey is 27359, comprising spectra of 14947 unique targets. The Gaia-ESO public survey data release is accompanied by a comprehensive description. Instructions on reading or displaying data in the Science Data Product (SDP) tabular data format can be found on the 1D spectrum data format help page.
