Abstract

<i>Context. <i/>At about 1000 days after the launch of <i>Gaia <i/>we present the first <i>Gaia <i/>data release, <i>Gaia<i/> DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magnitude 20.7.<i>Aims. <i/>A summary of <i>Gaia<i/> DR1 is presented along with illustrations of the scientific quality of the data, followed by a discussion of the limitations due to the preliminary nature of this release.<i>Methods. <i/>The raw data collected by <i>Gaia <i/>during the first 14 months of the mission have been processed by the <i>Gaia <i/>Data Processing and Analysis Consortium (DPAC) and turned into an astrometric and photometric catalogue.<i>Results. <i/><i>Gaia<i/> DR1 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 <i>Tycho<i/>-2 catalogues - a realisation of the <i>Tycho<i/>-<i>Gaia <i/>Astrometric Solution (TGAS) - and a secondary astrometric data set containing the positions for an additional 1.1 billion sources. The second component is the photometric data set, consisting of mean <i>G<i/>-band magnitudes for all sources. The <i>G<i/>-band light curves and the characteristics of ~3000 Cepheid and RR Lyrae stars, observed at high cadence around the south ecliptic pole, form the third component. For the primary astrometric data set the typical uncertainty is about 0.3 mas for the positions and parallaxes, and about 1 mas yr<sup>-1<sup/> for the proper motions. A systematic component of ~0.3 mas should be added to the parallax uncertainties. For the subset of ~94 000 Hipparcos stars in the primary data set, the proper motions are much more precise at about 0.06 mas yr<sup>-1<sup/>. For the secondary astrometric data set, the typical uncertainty of the positions is ~10 mas. The median uncertainties on the mean <i>G<i/>-band magnitudes range from the mmag level to ~0.03 mag over the magnitude range 5 to 20.7.<i>Conclusions. <i/><i>Gaia<i/> DR1 is an important milestone ahead of the next <i>Gaia <i/>data release, which will feature five-parameter astrometry for all sources. Extensive validation shows that <i>Gaia<i/> DR1 represents a major advance in the mapping of the heavens and the availability of basic stellar data that underpin observational astrophysics. Nevertheless, the very preliminary nature of this first <i>Gaia <i/>data release does lead to a number of important limitations to the data quality which should be carefully considered before drawing conclusions from the data.
