This table, part of the Gaia Data Release 3 has an entry for every Gaia observed source as listed in the Main Database accumulating catalogue version from which the catalogue release has been generated. It contains the basic source parameters, that is only final data (no epoch data) and no spectra (neither final nor epoch).
This table, part of the Gaia Data Release 2 has an entry for every Gaia observed source as listed in the Main Database accumulating catalogue version from which the catalogue release has been generated. It contains the basic source parameters, that is only final data (no epoch data) and no spectra (neither final nor epoch).
This table, part of the Gaia Data Release 1 has an entry for every Gaia observed source as listed in the Main Database accumulating catalogue version from which the catalogue release has been generated. It contains the basic source parameters, that is only final data (no epoch data) and no spectra (neither final nor epoch).
This table is a subset of DR1 GaiaSource comprising those stars in the Hipparcos and Tycho-2 Catalogues for which a full 5-parameter astrometric solution has been possible in Gaia Data Release 1. This is possible because the early Hipparcos epoch positions break some degeneracies due to the limited Gaia time coverage. This table contains a substantial fraction of the around 2.5 million stars in the Hipparcos and Tycho-2 catalogue. Many stars have been excluded due to several reasons, such as saturation, cross-match errors or bad astrometric solution.
This table, part of the Gaia Early Data Release 3 has an entry for every Gaia observed source as listed in the Main Database accumulating catalogue version from which the catalogue release has been generated. It contains the basic source parameters, that is only final data (no epoch data) and no spectra (neither final nor epoch).
These tables, part of the Gaia Focused Product Release (FPR), have an entry for every Gaia observed source as listed in the Main Database accumulating catalogue version from which the catalogue release has been generated. The FPR contains the following products: astrometry and photometry from engineering images taken in the Omega Centauri region; an environment analysis of quasars in search of gravitational lenses; extended radial velocity epoch data for Long Period Variables (LPVs); Diffuse Interstellar Bands (DIBs) from aggregated RVS spectra; and updated astrometry for Solar System objects.
ConeSearch service for the Hubble Catalog of Variables (HCV). The Hubble Catalog of Variables (HCV) is the first full, homogeneous, catalog of variable sources found in the Hubble Source Catalog (HSC), which is built out of publicly available images obtained with the WFPC2, ACS and WFC3 instruments onboard the Hubble Space Telescope. The HCV is the deepest catalog of variables available. It includes variable stars in our Galaxy and nearby galaxies, as well as transients and variable active galactic nuclei. The HCV contains 84428 candidate variable sources (out of 3.7 million HSC sources that were searched for variability) with V≤27mag; for 11115 of them the variability is detected in more than one filter. The data points in a light curve range from 5 to 120, the time baseline ranges from under a day to over 15 years, while ∼8% of variables have amplitudes in excess of 1mag.
ConeSearch service for the Hubble Source Catalog (HSC). The Hubble Source Catalog (HSC) is designed to optimize science from the Hubble Space Telescope by combining the tens of thousands of visit-based source lists in the Hubble Legacy Archive (HLA) into a single master catalog.
