\caption{Mean tangential velocities and dispersions (in \kms ) in galactic coordinates 
for stars of age groups  PMS, Pl\_ZAMS, UMa, Hya+ (split into dwarfs and giants),
and M stars without lithium detection for the individual study areas. 
The first two lines give the  average solar velocity for each study area.
The mean distance $\langle d \rangle$ and its scatter 
are given in pc. The number of stars used for the calculation of the mean values 
are given in parentheses.
