Here, $\psi$ is a spatial coordinate along the loop. Solid lines correspond to the gravitationally-stratified atmosphere with the coronal pressure scale-height, $\Lambda = 87$ Mm, and dotted lines to the gravity-free atmosphere ( $\Lambda \rightarrow \infty$ ).

$\begin{figure} \par\includegraphics[width=8.1cm,clip]{9266fig5.eps}\end{figure}$ Figure 3: A typical snapshot of time-signature of the mass density (grey scale; arbitrary units), collected at the loop summit. Here $\Lambda = 87$ Mm denotes the coronal pressure scale-height and spatial coordinate z and time t are measured in units of L and in seconds, respectively. Mass density is expressed in units of 10^-15 ${\rm kg~m^{-3}}$ .
