Radial observed HST F555W–F814 color profiles are compared to the predicted color profiles in the top panel for Nucleus 1, and in the middle panel for Nucleus 2. The observed HST colors that were corrected for foreground extinction and PSF effects. The relative reddening of the observed profiles is used to calculate the radially dependent internal extinction of the two Nuclei. Bottom panel: colored diamond symbols are the predicted radial M/L_I profiles for both nuclei, and the dashed black lines are the M/L_I, eff profiles that have been corrected for internal extinction.
