Analysis of the light curve of KIC 2436732, filtered at 80 days. Panel a: original light curve (light blue) and rebinned light curve (black). Panel b: wavelet decomposition (WPS) of the rebinned light curve. Panel c: GWPS (black) and Gaussian fit (green). Panel d: ACF of the rebinned light curve (black) and smoothed version of this ACF (blue). Panel e: composite spectrum of the rebinned light curve (black) and Gaussian fit (green). For each method, a dashed line indicates the returned period.
