CMDs for the LMC (upper left), SMC (upper right), globular cluster (lower left), and open cluster (lower right) samples. The intensity scale is logarithmic and the cell sizes are 0.01 μm⁻¹ × 0.1 mag (upper panels) and 0.02 μm⁻¹ × 0.2 mag (lower panels). The color bars at the right of each plot give the number of stars per cell, I note that they are very different from panel to panel. The upper x axes use Eq. (4) of L21a to transform from ν_eff to G_BP − G_RP.
