Input versus measured minus input Y_E-band magnitudes in the outer (top) and inner (bottom) regions of IC 10 using synthetic clusters produced with a Moffat profile and PARSEC isochrones. The dashed line indicates an offset of zero. Also plotted, for each magnitude bin, are the mean offsets with associated standard deviations (red) and, for comparison, the median cluster sample photometric uncertainties placed above at a ΔY_E value of 3 (grey).
