CMDs for the selected point sources corrected for the extinction and reddening and after the culls have been applied in the eight empty fields taken with ACS/WFC. Shaded regions are the same as those in Fig. 2: Blue for young stellar population including main sequence and helium burning stars, orange for intermediate aged AGB stars and red for old RGB stars. Dashed lines represent the 50% completeness limits. Photometric errors as derived from ASTs at (F606W − F814W)₀ = 1.0 are marked at (F606W − F814W)₀ = 2.0.
