Velocity dispersion profiles. Upper panel: circles show the dispersion values for the blue GCs (for fixed radial bins cf. Table 6) prior to quality selection and outlier removal. Dots are the values for the final blue sample. The dashed horizontal “error bars” indicate the radial range of a given bin; the bins used here are the ones indicated by the dotted lines in the lower panels of Fig. 8. The dispersion values from Paper I are shown as diamonds. In both panels, the vertical line at 25 indicates the first bin which covers the radius inside which blue and red GCs cannot be distinguished. Lower panel: the same for the red GCs.
