Caption: Figure 5.

V/I CMDs of the four radial regions we identified in the galaxy (see Figure 1) and used to recover the SFH (R1 being the innermost ellipse, R4 the outermost annulus); the dotted vertical lines are a rough reference of the blue edge of the MS (﹩{m}_{{\rm{F}}555{\rm{W}}}-{m}_{{\rm{F}}814{\rm{W}}}=-0.3﹩) and the red edge of the RGB (﹩{m}_{{\rm{F}}555{\rm{W}}}-{m}_{{\rm{F}}814{\rm{W}}}=2.5﹩).
