The left hand column shows time-distance diagrams take at the left (upper) and right (lower) sides of the sunspot. The wavelet scales displaying the greatest power are over plotted, with the zero crossings marking the height at which the wavelet was taken. The right hand columns displays the time-distance diagrams taken from the running difference movies. The dynamic up-flows are clearly seen. The position of the cross-cuts are shown in Fig. 1 and the same cross-cut positions are used for the left and right columns.
