BAX: A dedicated X-Rays galaxy clusters Database
R. Sadat, A., Blanchard and C. Mendiboure
We present BAX an ambitious project aiming at building a large database for X-rays clusters of galaxies information retrieval. The goal of BAX is to provide with all published data on the cluster basic properties with related references. This will allow to build catalogues of all known clusters with homogeneous and quality controlled values of the physical parameters. We expect BAX to become an essential tool for the astronomical communauty especially to optimize the cluster science return of XMM observations and in view of preparing Planck mission which will detect up to 10,000 individual galaxy clusters up to $z \approx 1$.
