Surface brightness profile of models with different central black hole masses. Symbols and colors are the same as Fig. 6. The red points are the observed profile (Sect. 2). The black line is the best no-IMBH model which falls slightly below the observed data. The blue, green and yellow lines represent models with black hole masses of 1%, 2% and 3% of the cluster total mass.
