The Gaia Mission is an ambitious attempt to measure a large part of our Milky Way with high precision. The Coordination Unit 9 of the DPAC consortium prepares the publications of the Gaia satellite mission. As part of CU9, I participated in Gaia@AIP, the Gaia data mirror at the Leibniz Institute for Astrophysics Potsdam (AIP).

The approx. 5 TB of the Gaia catalog at the AIP are stored in a PostgreSQL database. Special spherical queries can be performed using PgSphere. Access is via a web interface based on the Daiquiri framework.
