Notes. The last six are multi-dimensional data tables. The number of sources is approximate to the nearest million. HP = 3 145 728 (=HP9), 786 432, 196 608, and 49 152 for HEALPix level 9, 8, 7, and 6, respectively. gaia_source contains a subset of parameters from the astrophysical_parameters table. The mcmc_samples_gsp_phot contains 2000 samples for sources with G < 12 and for a random 1% of all other sources.
