The Gaia space observatory collects unprecedented positional and radial velocity measurements of about a billion stars in our Galaxy and throughout the Local Group. The AIP hosts the Gaia data as one of the external data centers along with the main Gaia archive maintained by ESAC.
What data is currently available now? Here you’ll find the expected Gaia date releases.

Gaia@AIP services – data access
Gaia@AIP hosts the data from Gaia data releases in sharded MariaDB database nodes. The data can be queried directly using the Structured Query Language SQL. Since the amount of data which such observation produce nowadays exceeds the Terabyte range, the full data set can be too large to be kept as a local copy for each user. Instead, the user can retrieve only the data subset he or she is interested in.
Here are some ideas what you can do about the queries beforehand.
You can also access the data via UWS clients.
For the use of Topcat and SAMP please look up the following tutorial
Hosted catalogues – database structures
Gaia@AIP hosts Gaia data releases along with the auxiliary catalogues.
The First Gaia Data Release is available for the public from 14.09.2016. It contains positions, G mean magnitudes and proper motions and parallaxes from Tycho2 for corresponding Gaia sources.
The Gaia Object Generator transforms the Universe Model (which itself is based on the Besançon galaxy model, Robin et al. 2003) into Gaia’s simulated catalogue data. For details, please refer to Luri et al. (2014).
GUMS-10 is the 10th version of the Gaia Universe Model Snapshot, a simulation of the expected contents of the Gaia cataloge run at the MareNostrum supercomputer.
The sum greater than the parts. Additional to the Gaia data we host catalogues for cross match purposes – that’s what SQL do best.
Auxiliary Gaia Quasar catalogue
The astrometric reference Tycho2 catalogue contain positions, proper motions, and two-color photometric data for the 2,539,913 of the brightest stars in the Milky Way.
RAVE DR5 will be available from September 19th 2016 and will be also available for the cross match at Gaia@AIP.
