GESiDR2 Database Release
update 2014-08-18 - The GESiDR2 was updated using revised WG15 and W13 files,see the
Known Issues page.
This release contains iDR2 recommended parameters and abundances as of
June 2014. The release usually contains metadata for the spectra and
the spectra themselves. Spectra observed as part of the GES Survey are
included. GIRAFFE spectra obtained from the ESO archive are also
included, but UVES spectra from this archive are not.
Initially the archive can be queried using the
freeform SQL form.
Additional access points will be provided in subsequent releases.
Please note that all use of parameters obtained from the archive in
publications and analyses leading to publications must conform with the
PI Policy Statement on the use of
iDR2 parameters, abundances and radial velocities.
iDR2 contains astrophysical parameters for around 32,000 stars, derived
by working groups WG10 - WG14 and homogenised by WG15. Abundances determined
by the analysis WGs 10-14 are available, but have not been homogenised by WG15
for iDR2. The WG reports on this page provide more information about the
derivation of WG results. In particular, refer to the WG15 report for details
of the homogenisation of the iDR2 recommended quantities and the policy on which
WG abundances may be used in publications.
The main content in the release is held in the following tables.

Known Issues page.
Working Group Reports
Consortium working groups 10 - 15 have prepared reports on the analyses that they performed
for iDR2. These reports are available for download as PDF documents:
