\begin{equation}
V^2 = \frac{2 G M_d}{R_d} y^2 [I_0(y)K_0(y)-I_1(y)K_1(y)]
\end{equation}
where $y\equiv R/(2R_d)$, $M_d$, the disk mass, is $6.4\times 10^{10}~M_{\odot}$ and $R_d$, the scale length, is 2.9 kpc.
For this curve, the epicyclic frequency is
\begin{equation}
\varkappa^2 = \frac{4 G M_d}{R_d^3} \left\{ \left[2 I_0(y)+yI_1(y)\right]K_0(y)-\left[y I_0(y)+I_1(y)\right]K_1(y)\right\}
\end{equation}
