Radial surface brightness profiles of the BCG+ICL in both I_E and H_E . The profiles require two Sérsic components to be adequately fit: a compact component (S1) and an extended component (S2). The transition between the profile being dominated by the compact BCG to being dominated by the extended ICL component occurs at a = 71 ± 13 kpc in I_E and a = 55 ± 6 kpc in H_E. The radius is not BCG-centric but is given by the semi-major axis radius a of the best-fit ellipse to each isophote with free central coordinates (see Fig. 7).
