“…The accompanying papers provide details as follows: Carrasco et al (2016) for the detailed definition of the calibration models, Riello et al (2017) for a description of the software solutions and processing strategies, and Evans et al (2017) for an in-depth analysis of the results of the photometric processing.…”

“…Some calibration effects have not yet been fully understood and there seem to be some systematics at the 10 mmag level particularly around G = 11 (see Evans et al 2017). The Gaia photometric catalogue covers the entire sky, providing measurements of the average brightness of sources down to magnitude 21 (at different levels of completeness at this stage) in a single photometric system.…”

“…For fainter stars the effect of the background can be noted, while for brighter stars the estimated errors are larger than expected due to effects related to different gate settings and saturation. For a comparison with the expected errors see Evans et al (2017). which is the main source of error for the faintest stars. The effect of saturation is evident for sources brighter than ∼6.5, while the three "bumps" in the middle are caused by the gates.…”

Context. This paper presents an overview of the photometric data that are part of the first Gaia data release. Aims. The principles of the processing and the main characteristics of the Gaia photometric data are presented. Methods. The calibration strategy is outlined briefly and the main properties of the resulting photometry are presented. Results. Relations with other broadband photometric systems are provided. The overall precision for the Gaia photometry is shown to be at the milli-magnitude level and has a clear potential to improve further in future releases.Key words. catalogs -surveys -instrumentation: photometers -techniques: photometric -Galaxy: general Article published by EDP Sciences A32, page 1 of 8 A&A 599, A32 (2017)

Stellar clusters in the Gaia era

Stellar clusters are important for astrophysics in many ways, for instance as optimal tracers of the Galactic populations to which they belong or as one of the best test bench for stellar evolutionary models. Gaia DR1, with TGAS, is just skimming the wealth of exquisite information we are expecting from the more advanced catalogues, but already offers good opportunities and indicates the vast potentialities. Gaia results can be efficiently complemented by ground-based data, in particular by large spectroscopic and photometric surveys. Examples of some scientific results of the Gaia-ESO survey are presented, as a teaser for what will be possible once advanced Gaia releases and ground-based data will be combined.

Context. Before the publication of the Gaia Catalogue, the contents of the first data release have undergone multiple dedicated validation tests. Aims. These tests aim to provide in-depth analysis of the Catalogue content in order to detect anomalies and individual problems in specific objects or in overall statistical properties, and either to filter them before the public release or to describe the different caveats on the release for an optimal exploitation of the data. Methods. Dedicated methods using either Gaia internal data, external catalogues, or models have been developed for the validation processes. They test normal stars as well as various populations such as open or globular clusters, double stars, variable stars, and quasars. Properties of coverage, accuracy, and precision of the data are provided by the numerous tests presented here and are jointly analysed to assess the data release content. Results. This independent validation confirms the quality of the published data, Gaia DR1 being the most precise all-sky astrometric and photometric catalogue to date. However, several limitations in terms of completeness, and astrometric or photometric quality are identified and described. Figures describing the relevant properties of the release are shown, and the testing activities carried out validating the user interfaces are also described. A particular emphasis is made on the statistical use of the data in scientific exploitation.
