Scaling relations between the Sérsic index n, the effective radius R_e, the central surface brightness μ_IE, 0, and mean effective surface brightness within R_e, ⟨μ_IE,e⟩, and the total magnitude measured using AutoProf/AstroPhot for all galaxies identified as cluster members. Magnitudes are corrected for Galactic attenuation. The red dashed line shows the 50% completeness of the sample, corresponding to M(I_E) = −11.33, assuming a mean Galactic attenuation A_IE = 0.33. The effective radius is in pixel units and surface brightness in mag arcsec⁻².
