Gaia DR3 CMD for stars selected as members of NGC 7790 by Hunt & Reffert (2024), plus two bright photometric members with divergent astrometric parameters (green diamonds). Several PARSEC isochrones (Bressan et al. 2012) displaced by the Gaia DM = 12.6 are shown. The solid lines are solar metallicity isochrones; the green line is a 105 Myr isochrone affected by AV = 1.70 mag, while the maroon one is a 130 Myr solar isochrone affected by AV = 1.65 mag, As reference, a 140 Myr Z = 0.010 isochrone with AV = 1.6 mag is shown as a dashed line. The best solution found by Hunt & Reffert (2024) is shown as a dotted line.
