        ($\sigma_{U}$, $\sigma_{V}$, 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 (values taken from Bensby et~al.~\cite{bensby} and
	Bensby et~al.~submitted).
