New reduced data products resulting from the Gaia-ESO Public Spectroscopic Survey (GES) are now available via the dedicated Phase 3 query interface at the ESO Science Archive Facility. The data release DR3 provides wavelength calibrated 1-dimensional spectra of point-like sources obtained with FLAMES from 31.12.2011 to 19.07.2014 under ESO program ID 188.B-3002, as well as a catalogue containing photometry and derived quantities (e.g. radial velocities, astrophysical parameters, lithium line strength, Halpha emission, abundances) for a fraction of the stars for which spectra are delivered. The total number of submitted data files is 44210, comprising spectra of 25533 unique targets. Included in this sample are 2342 ESO archive spectra, reduced and analysed within GES by the GES pipelines. The DR3 data products correspond to the Gaia ESO internal iDR4 release.

A supplemental data release DR3.1 is also provided. It contains updated versions of the DR3 spectra, reduced with the GES iDR5 pipelines, that supersede the GES iDR4 spectra.

The Gaia-ESO public survey data release is accompanied by a comprehensive description. Instructions on how to read or display data in the ESO/SDP tabular data format can be found in the 1D spectrum data format help page.
