Surface brightness profiles extracted from the boxes shown in Fig. 6. Data are plotted in blue and the model in red. Point-like sources are always excluded (the point-like source associated to the SG is also excluded; see the discussion in Sect. 4.4). Bottom panels report the data over model ratio. Orange vertical lines show the position of the SG (boxes A, B and D) and of CIZAJ1824 (box C).
