Comparison of CMD weights derived with different binning configurations for stars in subfield (l = 180°, b = 21°). In the left panel, both sets of CMD weights are derived with a bin size of 0.2 × 0.5 mag in the ﹩(g-r,r)﹩ diagram, but the grids are offset by half the bin size. In the right panel, ﹩{W}_{\mathrm{CMD}}^{1}﹩ is the same as those in the left panel, while ﹩{W}_{\mathrm{CMD}}^{3}﹩ is derived with a bin size of ﹩0.3\times 1.0﹩ mag in the ﹩(g-r,r)﹩ diagram. The size of the symbols indicates the number of stars that have the same values of CMD weights (based on the definition, all stars in the same CMD bin have the same value of CMD weight). The solid line indicates the 1:1 line, while the dashed lines indicate 1:2 and 2:1 lines.
