Top: PSD on logarithmic scale of KIC 2305930 smoothed using a 3-point boxcar function. The black curve corresponds to the original light curve. The pink curve is the PSD after correcting all the gaps with sizes less than 1 h (two long-cadence points), while the blue curve is the PSD after inpainting all the gaps less than 20 days. Bottom: ratio between the interpolated PSDs and the one with all the gaps. Both curves have been smoothed using a 300 point boxcar function.
