Illustration of the performances of GSP-Phot in cluster Messier 67. The PARSEC isochrone (indicated by the red dots in the panels) indicates the reference of log₁₀(Age/yr) = 9.5, A₀ = 0.11 mag, and solar metallicity. We also indicate with the vertical dashed blue lines the reference A₀, distance modulus, and [M/H]. Top left panel: Gaia CMD of M 67. Top right panel: G vs. gaia_source.teff_gspphot. The colours indicate the different best libraries (gaia_source.libname_gspphot). Middle left panel: G vs. gaia_source.azero_gspphot. Middle right panel: G vs. distance modulus derived from gaia_source.distance_gspphot. Bottom left panel: gaia_source.logg_gspphot vs. G_BP–G_RP (yellow dots). Bottom right panel: G vs. gaia_source.mh_gspphot.
