10.17876/gaia/edr.3Gaia EDR3European Space Agency (ESA)DPAC ConsortiumAstronomyLeibniz Institute for Astrophysics Potsdam (AIP)<p>The Gaia Early Data Release 3 (EDR3) enhances the DR2 catalogs by 118.79 million objects. It includes five-parameter astrometric solutions - positions on the sky, parallaxes, and proper motions - for more than 585 million sources, an additional pseudo-colour parameter for 800 million further sources (called six-parameter solution), and an additional 400 million sources with only positions, for a total of more than 1.8 billion sources with a mean G magnitude. The EDR3 release delivers an overall improvement in sky-coverage (almost complete down to 19 mag) and a great improvement in precision of both astrometric and photometric measurements. It spans 34 month of data collection by the Gaia satellite.</p> <p>The reference epoch for Gaia DR3 (both Gaia EDR3 and the full Gaia DR3) is 2016.0. Positions and proper motions are referred to the ICRS. The time coordinate for Gaia EDR3 is the barycentric coordinate time (TCB).</p>2020-12-03BY_NC_IGDataset
