Fig. 8
From left to right, the χ2 map for the radial velocity, the proper motion dispersion and the surface brightness profiles, for models with an IMBH mass of 2% of the model cluster mass, over the grid of initial parameters space. The numbers in black are the absolute χ2 over 400′′ radius. The absolute χ2 values inside 40′′ are shown in red to visualize the goodness of the fit in the central region for each model.
