homogeneous_stellar_parameters

Homogeneous stellar parameter catalog derived from APOGEE DR17, DESI DR1, GALAH DR3, Gaia RVS DR3, SDSS DR17 (optical) spectra. Contains the following parameter estimates, along with associated uncertainties: effective temperature [K] surface gravity [dex] chemical abundances for 20 elements, relative to H [dex] distances [log10, pc] ages [Gyr] It also contains extra metadata and quality flags: RA, Dec [deg] source (what is the parent survey that this object came from?) object_id (what is the unique identifier in the parent survey?) mahalanobis_dist, mahalanobis_percentile (Mahalanobis distance (percentile) of this embedding to training distribution of embeddings) iforest_score, iforest_percentile (Isolation Forest anomaly score (percentile) of this embedding) gmm_log_likelihood, gmm_percentile (log likelihood (percentile) of this embedding as determined by a K=10 GMM fit to the training set)
