Gaia@AIP2024 · Astronomical catalogue

SHBoost, catalogue of stellar properties derived from Gaia DR3 XP spectra, astrometry, and multi-wavelength photometry.

Gaia@AIP2023 · Astronomical catalogue

Radial velocity predictions for all Gaia DR3 stars without radial velocity measurements and with G-band magnitude brighter than 17.5. The predictions are generated by a Bayesian neural network model trained on the DR3 RVS sample. The model generates full posterior distributions, which are summarised in this catalogue as 4-component Gaussian mixtures.

The table contains atmospheric parameters (Teff, log(g), [M/H]), chemical abundances ([Fe/H], [alpha/M]), and their associated uncertainties for 886080 stars. These labels were derived using a convolutional neural network applied to the full Gaia data product in the form of RVS and XP spectra, parallaxes, and stellar magnitudes. As training labels, we used a set of 45000 stars with high-quality la

<p>This table contains a mapping from Gaia's Galactic to equatorial coordinates. The mapping is meant to be used with the GaiaFPR ISM Spectra table and enables IVOA ConeSearch capabilities. The transformation from galactic to equatorial coordinates follows <a href="https://gea.esac.esa.int/archive/documentation/GDR3/Data_processing/chap_cu3ast/sec_cu3ast_intro/ssec_cu3ast_intro_tansforms.html#SSS1

<p>This table provides the list of input catalogues that have been used to select any given source that was analysed by the Gravitational Lens module and published in the lens candidate table.Each source may have been cross-matched to more than one catalogue and therefore can have several entries in the table.For the FPR, the catalogues considered for this selection are mostly external, although s

<p>This table contains the individual observations that have been discarded from the analysis of the gravitational lenses around the list of sourceIds tabulated in the lens candidate table. These are observations that could not be associated with any of the components assigned to the source of interest.</p>

<p>The Gaia Focused Product Release presents five data products which showcase a subset of the improvements and new data products expected for Gaia DR4. The FPR data products are based on the Gaia observations collected over the same period as used for Gaia DR3 (except for the astrometry and photometry for ω Centauri and the updated Solar System objects astrometry). These data are products based o

<p>Sources based on Service Interface Function (SIF) images of very dense regions in the sky. These sources build an add-on catalogue to the nominal Gaia catalogue. Nominal and SIF detections were not mixed to create these sources. These Sources are thus obtained from SIF image detections only. Sources already present in the nominal catalogue were removed from the SIF add-on catalogue.</p>

<p>Table <code>gsc23_best_neighbour</code> lists each matched Gaia object with its best neighbour in the external catalogue. The cross-match algorithm is not symmetric and searches Gaia sources counterparts in GSC2.3.
