Top left panel: SB profile of the Rc-band BCG+ICL map along the SE (blue) and NW (red) directions. Points from the extra slit along the SE direction are highlighted with a yellow circle, while the σ_sky level is shown by the dotted line. The generic Sérsic (gs), generic Sérsic with high index (gshn), double de Vaucouleurs (dd), de Vaucouleurs plus generic Sérsic (ds), and de Vaucouleurs plus generic Sérsic with low index (dsln) best fit models are shown by the dot-dot-dot-dashed, long-dashed, dot-dashed, short-dashed, and solid lines, respectively. Top right panel: zoomed version of the SB profile in the radial range 20 ≤ R ≤ 100 to highlight the asymmetric radial distribution of the SB profile. Bottom Left panel: fit residuals along each direction for the single component profiles, i.e., the generic Sérsic (circles) and the generic Sérsic with high index (triangles). Bottom right panel: fit residuals along each direction for the double component profiles, i.e., the double de Vaucouleurs (upside-down triangles), de Vaucouleurs plus generic Sérsic (stars), and de Vaucouleurs plus generic Sérsic with low index (squares).
