Color–magnitude diagram of NGC 6802 stars. Stars with photometric membership probability greater than 50% are shown as small black dots. Cluster members (black filled circles) and non-members (black crosses) identified by spectral RV are also plotted. Red, blue, and green solid lines represent the PARSEC isochrones with ages of 0.8, 0.9, and 1.0 Gyr, respectively. For all three isochrones, [Fe/H] = 0.1 dex, E(B−V) = 0.86, and (m−M)₀ = 11.4.
