Density plot of the comparison of the temperature (top), surface gravity (middle), and global metallicity (bottom) provided by GSP-Phot (left) and GSP-Spec (right) with APOGEE DR16. GSP-Phot has been filtered with parallax_over_error > 10, and teff_gspphot < 10 000. GSP-Spec parameters have been filtered with flags_gspspec[1,4,8,13] = 0 for T_eff, flags_gspspec[2,5,8,13] = 0 for log g, and flags_gspspec[3,6,8] = 0 for [M/H]. The RVS spectrum signal-to-noise ratio was not filtered.
