TL;DR: Gaia Early Data Release 3 (Gaia EDR3) as mentioned in this paper contains results for 1.812 billion sources in the magnitude range G = 3-21 based on observations collected by the European Space Agency Gaia satellite during the first 34 months of its operational phase.

TL;DR: Gaia Early Data Release 3 (Gaia EDR3) as discussed by the authors contains results for 1.812 billion sources in the magnitude range G = 3 to 21 based on observations collected by the European Space Agency Gaia satellite during the first 34 months of its operational phase.

TL;DR: The third data release of the European Space Agency's Gaia mission, GDR3 as discussed by the authors , contains the same source list, celestial positions, proper motions, parallaxes, and broad band photometry in the G, G$BP}$, and G$RP}$ pass-bands already present in the Early Third Data Release.

TL;DR: The first Gaia Data Release contains the Tycho-Gaia Astrometric Solution (TGAS) component by means of the astrometric data for open clusters as discussed by the authors, which is a subset of about 2 million stars for which, besides the position and photometry, the proper motion and parallax are calculated using Hipparcos and Tycho 2 positions in 1991.

TL;DR: In this paper, a clean and well-characterised catalogue of objects within 100 pc of the Sun from the Gaia Early Data Release 3 is presented, which contains at least 92% of stars of stellar type M9 within 100pc of the sun.
