Distribution of fitting parameters using the double exponential profile in the I_E band for Type II (down-bending break in higher panels) and Type III (up-bending break in lower panels) profiles. The scalelengths of the discs and down-bending break radii are compared to the effective radii from the main Perseus catalogue Cuillandre et al. (2025b). First panel: Distribution of the central surface brightness of the discs. Second panel: Distribution of the break surface brightness compared to the central surface brightness of the discs. Third panel: Distribution of first disc scalelengths. Fourth panel: Distribution of second disc scalelengths. Fifth panel: Break radii compared to the effective radius of the galaxy.
