F.10 hernquist

potname=hernquist potpars=$\Omega,M,r_c$

Potential is given by: \begin{displaymath}
\Phi = - { M \over {(r_c+r)}}
\end{displaymath} and mass \begin{displaymath}
M(r) = M { r^2 \over {(r+r_c)}^2 }
\end{displaymath} and density \begin{displaymath}
\rho = { M \over {2\pi}} {r_c \over r} { 1 \over {(r+r_c)}^3}
\end{displaymath}
