\caption {Coronal seismology using $P_{1}/2P_{2}$: density ratio 
$\rho_{\rm apex}/\rho_{\rm base}$.
%Using the results in
%Fig.~\ref{fig:r3}, combined with the loop
%oscillation observations for cases C, D and E \citep{verwichte2004,tvd2007}, we
%deduce the density ratio $\rho_{\rm apex} / \rho_{\rm base}$ in the loops
%for different equilibrium profiles. A ``$-$'' sign means that this ratio cannot be
%achieved with that particular equilibrium profile.
