Wavelet and Fourier analysis of the temporal evolution for AIA (left panel) and EUI (right panel). For each panel, the variance-normalized light curve is shown at the top left. Below is the whitened Morlet wavelet spectrum (i.e. normalized to the model of background power). The right and size plots show the time-averaged wavelet (thick line) and Fourier (histogram) power spectra. The fitted model of background power is plotted in red, along with its components (dashed red). The dark and light orange curves give the 99% local and global confidence levels for the time-averaged wavelet spectrum, respectively. The grey line represents the 99% global confidence level for the Fourier spectrum. In each panel, the middle plot represents the same information with whitened spectra.
