\caption{Parameters of models~A,~B,~C (from Kaufmann \&~Contopoulos
\cite{Kaufmann1996}). The units are $\mbox{km}^2~\mbox{s}^{-2}~\mbox{kpc}^{-1}$ for
$A$, $\mbox{kpc}^{-1}$ for $\varepsilon_{\rm s}$, $\varepsilon_{\rm d}$,
$\kappa_1$ and $\kappa_2$, $\mbox{kpc}$ for $r_1$, $r_2$, $\Delta$,
$a$, $b$, $c$, and $b_{\rm h}$, $10^{10}~M_\odot$ for $M_{\rm h}$, $M_{\rm b}$,
$\mbox{km}~\mbox{s}^{-1}~\mbox{kpc}^{-1}$ for $\Omega_{\rm p}$, and
$M_\odot$/pc$^2$ for $\Sigma_0$. Model~A$'$ has the same
parameters as model~A, except for the spiral amplitude $A=1000$ and
the pitch angle $i_0=-9^\circ$. Model~B$'$ has the same parameters
as model~B except for $A=2500$, $M_{\rm b}=0.09$, $i_0=-8^\circ$,
$\Omega_{\rm p}=30.5~$$\mbox{km}~\mbox{s}^{-1}~\mbox{kpc}^{-1}$.}
