Heavily smoothed (5 μHz boxcar filter) power density spectrum of the about 540 and 1000 day-long SC (grey line) and LC Kepler time series (light-red line), respectively, of KIC 5596656. The black lines correspond to the best-fit model for the SC data with (full line) and without (dashed line) the Gaussian component. The red lines indicate the SC model corrected for the amplitude suppression due to the longer sampling. The vertical dotted line marks the Nyquist frequency for the LC sampling.
