Fig.~\ref{Zhist1}. Scale heights and number densities are
given for each fitted component. For a two-component fit no "thick disk''
values were determined. \label{fits}}

\medskip
$^a$ Values of $N(0)$ come from the numerics of the orbit statistics
and cannot be used as number of stars per unit volume. \\
$^b$ Halo values are based on three stars only (see Sect.~\ref{res3}).
