\label{eqn:kr}
k_r^2 = \frac{ \big(L_\ell^2 - \omega^2 \big) \big(N^2 - \omega^2 \big) }{v_s^2 \omega^2} \, .
\end{equation}
{\bf Deep within an evanescent region where $N^2 \ll \omega \ll L_\ell^2$, equation \ref{eqn:kr} evaluates to $k_r \sim \sqrt{\ell (\ell +1)}/r$, and equation \ref{eqn:integral} yields the expression for $T$ in equation \ref{eqn:integral2}.} The
second ethe which evaluates approximately to the expression in equation \ref{eqn:integral2}. The wave crossing time for acoustic waves is
\begin{equation}
t_{\rm cross} = \int^R_{r_2} \frac{dr}{v_s} \, .
