\caption{\label{tab5} 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. (\cite{drin03a}) from Keck
spectroscopy.}
