Perturbations in various physical parameters of the four pores of interest. The left panels show the area (solid blue) and pore-averaged intensity (dashed red) fluctuations, and the pore-averaged CP (solid green) and pore-averaged LOS velocity (dashed black) oscillations are presented in the right panels. The plots in a given row show the results for one pore, as indicated left of the figure. All signals are detrended (linearly) and apodized (using a Tukey window). Low frequencies (< 1 mHz) have been filtered out. The amplitudes are therefore not preserved and thus are all shown in arbitrary units (a.u.).
