The footpoint is highlighted by the solid white lines. b) The time-space diagram of the intensity running difference taken over the time series at each position along the loop. The dashed white lines indicate the gradient of the diagonal bands. c) The intensity oscillation in data numbers observed in a cut taken at position p=4 along the loop, this position shows the clearest evidence of an oscillation. The left hand diagram is the data including the background intensity trend, with the right hand side being the data with an average background level removed and the linear trend (dashed line) corrected for. d) The wavelet diagram at position 4 along the loop. The dashed line indicates the cone of influence and the solid lines indicate the contours of 99% confidence. The darker regions indicate the areas with higher wavelet power. Only the regions between the time axis and the dashed lines, representing the cone of influence, showing power above the 99% confidence level are considered reliable.

$\begin{figure} \par\mbox{\subfigure[]{\includegraphics[width=8cm]{figs/4041_3a.eps} } \subfigure[]{\includegraphics[width=8cm]{figs/4041_3b.eps} }}\end{figure}$ Figure 3: a) The time-space diagram of the intensity running difference taken across the loop, labelled 3 in Fig. 2a (as opposed to along) at 0057 UT on June 13th 2001. In this time-space diagram position is defined to be the position along loop 3. We see that at 0057 UT the oscillation is mainly confined around position 10 across the loop structure, corresponding to strand 2 from Fig. 2a, at this point in time. b) The time-space diagram along loop 3, taken on the same day at 0138 UT. We now see the intensity oscillation to be centred around position 8, this corresponds to strand 1 in Fig. 2a. Note that the original oscillation, at position 10, is no longer present.

The dominant period is clearly seen at around 300 s. There is a second peak at around 200 s, as was found by De Moortel et al. (2002a). b) The histogram showing the distribution for all 63 examples observed. Here we see the dominant period at around 300 s with a second peak at around 160 s which is less pronounced.
