Comparison between measured and model-predicted velocity dispersion profiles. In black, we show the profile obtained from the kinematic measurements (red data points) of the cluster member 83 064 in M0416. As solid orange lines, we plot 100 profiles obtained with the dynamical model by sampling the posterior distributions of the free parameters, drawn from the MCMC optimization and shown in Fig. 4. The distance from the galactic center is reported in arcseconds (bottom) and kiloparsecs (top).
