\caption{\label{threesome}Table showing the mean velocities $\overline{v}$ and velocity dispersions~$\sigma_v$ of all, only bright ($V<20$~mag) and only faint ($V>20$~mag) Fornax members. 
Samples considered
are: the entire~FCOS-sample (FCOS-1 and~FCOS-2); the~FCOS-sample corrected
for the systematic velocity differences between~FCOS-1 and~FCOS-2 (see Sects.~\ref{syserr} 
and~\ref{vrad}); and the shift corrected~FCOS-sample + additional Fornax members
from Dirsch et~al. (\cite{Dirsch04}) + the 2 UCDs not observed in the~FCOS, taken from Karick et~al.
(\cite{Karick03}). 
The column 
"Dif. Conf.'' gives the confidence limit in percent for the hypothesis of the bright and 
faint value being different,
derived with a t-test for the means and with an F-test for the dispersions.}
