Comparison between the light curves obtained with the three high pass filters for KIC 1164583 (from left to right, 20, 55, and 80-day filter respectively). (a) KEPSEISMIC light curve. (b) Wavelet power spectrum (left) and global wavelet power spectrum (right). The grid represents the cone of influence of the reliable periodicity. High-amplitude power are highlighted by black and red whereas green and blue denote low-amplitude power. (c) Auto-Correlation Function. (d) Composite spectrum (black) and corresponding best fit with multiple Gaussian profiles (green). In all panels, the dashed line shows the position of the extracted rotation period.
