Surface brightness profiles of Sex A (upper panel) and Sex B (lower panel) in V band obtained by joining surface photometry from HE06 (open triangles) and star counts (open squares) profiles. The continuous lines are the Sérsic models that best fit the profiles. The dashed line in the upper panel is the Sérsic model that best fits the observed profile for Rϵ> 1.8′, i.e, excluding the flat portion of the profile near the centre of the galaxy. The level of the background (bkg) and the associated uncertainty are also shown.
