\caption{Characteristic velocity dispersions 
($\sigma_{U}$, $\sigma_{V}$, and $\sigma_{W}$) in the thin 
disk, thick disk, and stellar halo, used in 
Eq.~(\ref{eq:probabilities}). $X$ is the observed fraction of stars for 
the populations in the solar neighbourhood and $V_{\rm asym}$ is the
        asymmetric drift. The values fall within the intervals that are 
characteristic for the thin and thick disks, see Sect.~\ref{sec:intro}.}
