Gaia Data Release 1 Summary of the astrometric, photometric, and survey properties

Anthony G. A. Brown, +590 more
TL;DR: The first Gaia data release, Gaia DR1 as discussed by the authors, consists of three components: a primary astrometric data set which contains the positions, parallaxes, and mean proper motions for about 2 million of the brightest stars in common with the Hipparcos and Tycho-2 catalogues.
Journal ArticleDOI

Gaia Data Release 2: The astrometric solution

Lennart Lindegren, +92 more
TL;DR: In this article, the authors describe the input data, models, and processing used for the astrometric content of Gaia DR2, and the validation of these results performed within the ASTR task.
Journal ArticleDOI

Gaia Data Release 1. Open cluster astrometry: performance, limitations, and future prospects

F. van Leeuwen, +592 more
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.
Journal ArticleDOI

Gaia Data Release 2: The astrometric solution

Lennart Lindegren, +92 more
TL;DR: Gaia Data Release 2 (Gaia DR2) contains results for 1693 million sources in the magnitude range 3 to 21 based on observations collected by the European Space Agency Gaia satellite during the first 22 months of its operational phase as mentioned in this paper.
