Example of the removal of sharp peaks in the Fourier domain for one of the Kepler targets (KIC000757280). Top panel: the absolute value of the Fourier transform of Kepler data (blue line) alongside the measured PSD, which does not resolve the peaks (orange line) Middle panel: notch filters designed by the pipeline for the identified peaks. Bottom panel: Fourier transform of the data after applying the notch filters, showing the peaks removed.
