Description

A list of new sources based on Service Interface Function (SIF) engineering images of very dense regions in the sky (in this case the Omega Centauri globular cluster), building an add-on catalogue to the nominal Gaia catalogue. Nominal and SIF detections were not mixed to create these sources. The new sources are thus obtained from SIF image detections only. Sources already present in the nominal catalogue were removed from the SIF add-on catalogue.

The publication consists mainly of:

  • Astrometric information (position, parallax and proper motion for 526,457 new Gaia sources as derived from SIF images of the Omega Centauri region (with 130 additional sources with positions only).
  • Photometric information (mean G magnitude and flux) for these same 526,587 sources as derived from the SIF images.

Mission description Gaia is a European space mission providing astrometry, photometry, and spectroscopy of more than 1000 million stars in the Milky Way. Also data for significant samples of extragalactic and Solar system objects is made available. The Gaia Archive contains deduced positions, parallaxes, proper motions, radial velocities, and brightnesses. Complementary information on multiplicity, photometric variability, and astrophysical parameters is provided for a large fraction of sources.
