  • 1. ROR icon University College London

Description

Output stellar ages derived by the SIDRA-XP model, as decribed in "Towards Galactic Archaeology with Inferred Ages of Giant Stars From Gaia Spectra"

Included parameters: SIDRA-XP’s predicted stellar ages (pred_logAge), stellar parameters obtained from Fallows and Sander 2024,  [Fe/H] (fe_h), effective temperature (teff), surface gravity (logg), [C/Fe] (c_fe), [N/Fe] (n_fe), and [a/M] (alpha_m) alongside their uncertainties, (fe_h_unc), (teff_unc), (logg_unc), (c_fe_unc), (n_fe_unc), (alpha_m_unc), galactocentric X (Xgal), galactocentric Y (Ygal), galactocentric Z (Zgal), observed distance (d_obs), Gaia DR3 source IDs are included alongside Gaia’s parameters, (parallax), (l), (b),  (phot_g_mean_mag), (nu_eff_used_in_astrometry), (pseudocolour), (ecl_lat), (astrometric_params_solved).

Note the fits file, ruwe_data_ages_datasampling_results_optuna_model.fits,  is 0.403 GB.
