Gaia DR3 Contributions (gaiadr3_contrib)

Description

Contributions using Gaia DR3 catalog tables

Tables

  estimates_gdr3_rv (gaiadr3_contrib.estimates_gdr3_rv)

Bayesian Estimates for Gaia DR3 Radial Velocities

  Catalog of atmospheric parameters and chemical abundances from Gaia RVS spectra with convolutional neural network (gaiadr3_contrib.cnn_gaia_rvs_catalog)

The table contains atmospheric parameters (Teff, log(g), [M/H]), chemical abundances ([Fe/H], [alpha/M]), and their associated uncertainties for 886080 stars. We also provide a boundary_flag that should be used to filter the stars outside of the training sample limits. We recommend using flag_boundary = '00000000' for science applications.
