The table has 3273041 rows, 21 columns.
Description
Stellar astrophysical parameters of the golden sample of F, G, K, and M stars from DR3-DPACP-123. Values are identical to the ones in the astrophysical_parameters and astrophysical_parameters_supp tables, but only those values retained after filtering are copied over.
