GESiDR4 Database Release

For details of known issues and problems with GESiDR4 see the Known Issues page.

GESiDR4 is a full release. All observations from the beginning of the survey until July 2014 are included, which is two and a half years of observations.

This release contains iDR4 Recommended Parameters, derived products (individual element abundances, chromospheric activity, circumstellar disk detection etc.) and radial and rotational velocities as of February 2016. It also contains the stacked spectra derived from observations made for the Gaia-ESO Survey during iDR4 and tables of metadata summarising these spectra.

GESiDR4 is a release internal to the GES Consortium and only available to GES Co-Investigators. If you are a GES Co-Investigator then in order to access the archive you must obtain a login profile from your local GES Community Contact, if you have not already done so. Every institution in the Consortium has a Community Contact. See the list of community contacts to identify your local contact.

If no community contact is listed for your institution please contact either Clare Worley (ccworley@ast.cam.ac.uk) or Anna Hourihane (aph@ast.cam.ac.uk).

If you encounter login or other technical problems then please report them by e-mail to ges-support@roe.ac.uk.

The structure of the release, in terms of the tables present and their constituent columns, is the same as the previous release. The sizes of the main tables are as follows:

Working Group Reports

• WG11 Interim Report (8.2 Mbyte),
• WG12 Quality Control Report (131 Kbyte),
• WG13 Report (4.0 Mbyte),
• WG14 Interim Report (mainly presenting iDR2iDR3 results; 2.6 Mbyte),
• WG15 Report (8.3 Mbyte).
