Density maps for four of the M 83 target galaxies (ESO381-018, ESO444-78, IC 4247, and ESO381-20, ordered by absolute magnitude), each divided in five stellar evolutionary phases. These are: MS, BL, RSG, luminous AGB and RGB, ordered by increasing age. The stellar density values are listed along the colorbars, in units of number of stars per 0.1 kpc2. 10 equally spaced isodensity contours are drawn starting at the 1σ significance level up to the peak significance level. The peak levels are: for ESO381-018: MS = 2σ, BL = 3.8σ, RSG = 3.8σ, AGB = 3.6σ, RGB = 4σ; for ESO444-78: MS = 2σ, BL = 2.5σ, RSG = 3σ, AGB = 3σ, RGB = 4σ; for IC 4247: MS = 2.6σ, BL = 4.7σ, RSG = 5σ, AGB = 4.2σ, RGB = 4.7σ; for ESO381-20: MS = 3σ, BL = 3.5σ, RSG = 3.4σ, AGB = 3.5σ, RGB = 3.7σ. The center of each galaxy is indicated with a black cross. Just as a reference among different frames, we also overplot in red the ellipse corresponding to the projected major axis radius at the isophote level 25 mag arcsec-1 in I-band (taken from Sharina et al. 2008).
