Caption: Figure 8.
Fourier amplitude periodograms derived from the TESS light curve of RY Lep from Sector S06. From top to bottom, the panels show the periodogram of original data, after subtraction of four frequencies, and after subtraction of twelve frequencies. The blue horizontal line marks the signal-to-noise ratio (S/N) threshold of 5.
