Axial surface-brightness profiles (yellow symbols) and fits (continuous black curve) for ESO 533-4 (top) and NGC 6010 (bottom). The fitted disc and CMC contributions are indicated with dashed lines. The small vertical black lines indicate the break radii. The red vertical lines indicate the outermost fitted point. The vertical green lines indicate the axial extent of the 0.2 r₂₅< |x| < 0.5 r₂₅ and 0.5 r₂₅< |x| < 0.8 r₂₅ vertical surface-brightness profiles. The horizontal lines indicate the μ = 27 mag arcsec^-2 level. The grey dotted curves indicate the unconvolved disc fitted model.
