Notes. Columns (1) and (2) label the samples, and the number of GCs is given in (3). Columns (4) and (5) list the mean and median radial velocity (in km   s-1). The velocity dispersion in (km   s-1) as computed with the Pryor & Meylan (1993) formula is given in Col. (6). Columns (7) and (8) give the skewness and the reduced kurtosis, the uncertainties were estimated using a bootstrap with 999 resamplings. The p-value returned by the Anderson-Darling test for normality is given in Col. (9).
