The Strasbourg astronomical data center (CDS) provides reference astronomical services:

  • SIMBAD is the reference database for identification and bibliography of astronomical objects (outside the solar system).
  • VizieR is a catalogue service for large sky surveys, catalogues and tables published in academic papers, and more and more other data associated to publications.
  • The interactive sky atlas Aladin provides an interactive portal to access image collections and databases available via Virtual Observatory protocols.
  • The CDS cross-match service allows to do positional cross-matching of very large catalogues.
