Density (upper panel) and velocity dispersion (lower panel) profiles for light (black) and heavy (orange) component of Sim 6 at 7 Gyr. Uncertainties on the profile values are obtained by means of a bootstrap resampling. The differences between the two density profiles indicate the presence of mass segregation, whereas the differences between the two velocity dispersion profiles may be interpreted as due to the effects of partial energy equipartition. The vertical lines indicate the half-mass radius of the component under consideration.
