Top: surface-brightness profiles of the four axial bins of ESO 533-4 (large filled circles) and fits produced with a single disc component (dotted lines). The vertical dot-dashed grey lines indicate the range of heights considered for each fit. Each of the panels contains some information about the fits: the faintest surface-brightness level that was considered for the fit (μ_l), the maximum height considered for the fit (z_l), the dynamic range of the fit (Δμ), and the root mean square deviation of the fit (μ_rms). Bottom: same as the top but for NGC 6010.
