CMDs with Gaia photometry showing the BASE-9 results for each cluster. Field stars are marked in light gray and stars classified as members using Gaia kinematics and distances but are rejected by BASE-9 are marked by a red “x.” Single star BASE-9 members are marked in dark gray and BASE-9 binary members are colored according to the mass ratio of the binary. The black horizontal bars mark the magnitude range over which MS stars with a primary mass of 0.6 M _⊙ ≤ M ₁ ≤ 1 M _⊙ are found. The red line shows a PARSEC isochrone created from the median cluster parameters from our BASE-9 analysis.
