Table 5: Average values for radial velocity and velocity dispersion measurements: (1) mean of all fits; (2) as (1), but with 2-sigma clipping; (3) mean excluding Na and Ca region and combined region. The values in bold face are those used for further analyses. The velocity dispersion of UCD1 was derived by Drinkwater et al. (2003) from Keck spectroscopy.
