Top panels: single raw image from the burst. Middle panels: reconstructed frames with the recurrent network. Lower panels: azimuthally averaged Fourier power spectra of the images. Left column: results from the continuum image at 6302 Å. Right column: results at the core of the 8542 Å line. All power spectra have been normalized to the value at the largest period (but not shown in the plot because it is outside the displayed range).
