About the Centre de Données astronomiques de Strasbourg (CDS)
The Strasbourg astronomical Data Center (CDS) is a data center dedicated to the collection and worldwide distribution of astronomical data and related information. It is located at the Strasbourg Astronomical Observatory, France.
The CDS hosts the SIMBAD astronomical database, the world reference database for the identification of astronomical objects.
The CDS' goals are to:
- collect all of the useful information concerning astronomical objects that is available in computerized form: *observational data produced by observatories around the world, on the ground or in space;
- upgrade these data by critical evaluations and comparisons;
- distribute the results to the astronomical community;
- conduct research, using these data.
The CDS has signed international exchange agreements with
- NASA (ADC),
- Japan's National Astronomical Observatory in Tokyo,
- the Russian Academy of Sciences,
- the UK PPARC Starlink network,
- China's Beijing Observatory,
- the University of Porto Allegre in Brazil,
- the University of La Plata in Argentina,
- and India's InterUniversity Center for Astronomy and Astrophysics.
The CDS plays, or has played, a part in most of the major astronomical space missions: generating guide star catalogues (EXOSAT, IRAS, Hipparcos, HST, ISO, SAX), helping to identify observed sources (Hipparcos, Tycho, ROSAT, SIGMA), or to organize access to the archives (IUE), etc. CDS contributes to the XMM Survey Science Center, with the High-Energy group of Strasbourg astronomical observatory
