Fourier amplitude periodograms derived from the TESS light curve of RY Lep from the combined S32 and S33 sectors. From top to bottom, the panels show the periodogram for the original data, after subtracting four terms, after subtracting seven terms, and after subtracting 36 terms. The blue horizontal line marks the S/N threshold of 5.
