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 Gaia data is currently available now? Here you’ll find what to expect from the Gaia data releases.

More information on the currently available data releases on the ESA webpage:

Gaia@AIP services – data access

Gaia@AIP hosts the data from Gaia data releases in a PostgresQL database. The data can be queried directly using the Astronomical Data Query Language (ADQL) or Postgres flavour of SQL (Structured Query Language). 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.

This section explains how to use the Query interface and gets you started with some query examples (will be added soon). Your query results are stored in your Private user database

You can also retrieve the data via the TAP interface using Topcat or a scripted access.

Here are some ideas what you can do about the queries beforehand – How do I get my query to work?.

Hosted catalogues – database structures

Gaia@AIP hosts Gaia data releases along with the auxiliary catalogues. Here you’ll find information of what is hosted on Gaia@AIP.
