(Continued figure). [Continuation of the legend on the previous page]. Red and blue dashed lines: linear fits performed to data within the selected radial limits defining the inner and outer discs, respectively. Black dashed vertical and horizontal lines: values of the radius and surface brightness of the antitruncation (R_brkIII, μ_brkIII). The photometric parameters of the breaks and the inner and outer discs resulting from the piecewise fits are shown in each panel (the surface brightness values are provided in mag arcsec^-2 and the scalelengths are in kpc). R_1/2 corresponds to the half-light (or effective) radius of the whole galaxy and R_lim is the radius at which the limiting magnitude of the profile is achieved. R₂₅(R) refers to the radius of the isophote with μ_R = 25 mag arcsec^-2. R₂₅(R) is not equivalent to R₂₅ used throughout the manuscript (defined in the B band instead).
