(Upper panels) Comparison of best-fit models (gray) and data in key wavelength regions for M31-B193 (MR GC; orange) and M31-B058 (MP GC; blue). (Lower panels) Comparison of the percentage difference between the best-fit model and data regions for M31-B193 and M31-B058. The data have been smoothed and so the pixels are highly correlated. In the gray band we show the uncertainty for one of the GCs, M31-B058, as the uncertainties are comparable. The residuals between MR and MP GC are also comparable.
