Surface brightness profile of VV124 in r band obtained by joining surface photometry (for r_ϵ ≤ 72″; Sect. 2.4) and star counts (for r_ϵ > 72″) profiles. The continuous line is the Sersic model that best-fits the surface photometry. The level of the background (bkg, dotted line) and the associated uncertainty (dashed lines) are also reported. The error bars from surface photometry are typically smaller than the dimension of the points.
