Panel rows from top to bottom: g′−r′ color, effective radius (R_e), Sérsic index (n), Residual Flux Fraction (RFF), and mean effective surface brightness () of the Fornax dwarf galaxies as a function of their cluster-centric distance. The columns correspond to different luminosity bins. The lines and shaded areas show the bin means and uncertainties of the mean for the parameters. The green and purple colors correspond to the values when the projection effects are taken in account (dE(nN)s and late-types excluded from the inner parts as found in Sect. 3.2), and when raw data is used, respectively. The late-type and early-type dwarfs are shown with the blue and red symbols, respectively. The unfilled symbols correspond to the galaxies excluded from the inner parts in order to minimize the projection bias. The ρ parameter indicates Spearman’s correlation coefficient for the correlation of the parameter with distance, and its uncertainty.
