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 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

A deconvolution map-making method for experiments with circular scanning strategies

TL;DR: In this article, a deconvolution map-making algorithm was proposed to remove the effects of arbitrary beams from the maps and demonstrate the effects on the maps of ignoring beam asymmetries.
