Caption: Figure 6.
Two-component GMM fits to the F115W − F200W (top) and F150W − F200W (bottom) color distributions at the 95% and 97%completeness levels. Histograms show our MACS0416 GC data, with individual Gaussian components (dashed lines) and total fits (solid lines) overlaid. Error bars in the upper-left corners display the photometric color error in the displayed completeness level.
