CMDs for the MIST models used in this work as a function of Pan-STARRS i-band magnitude at d = 1 kpc and Pan-STARRS r − z color. The left panel shows the models used with [Fe/H]_init= +0.02, with the rough locations of the main-sequence and post-main-sequence evolutionary phases indicated. The underlying mass tracks are shown as light gray lines, with the actual models used shown as points and colored by $\mathrm{log}{M}_{\mathrm{init}}$ . The right panel shows the entire collection ∼750,000 models defined over [Fe/H]_init= −4.0 to +0.5 that are used in this work.
