  \caption{The first eight largest eigenvalues~$\sigma$ for 
    the free wave solutions of Eq.~(\ref{eq:AppPsiSimp}).
    Values are normalized to the frequency of the ISCO,~$\Omega_{\rm isco}=6^{-3/2}$.
    Results are given for 3~azimuthal modes~$m=1,2,5$ for 
    the Newtonian, as well as for the Schwarzschild gravitational field.
    Where no inner Lindblad resonance exist, this is represented by~$-$.}
