PERIOD04 periodograms for the outside-eclipse TESS residuals. The first and second panels show the amplitude spectra of the 120 and 200 s residuals, respectively, while the third and bottom panels are obtained using the entire short-cadence data, prewhitening the most dominant frequency (f₁) as indicated by a vertical green line and all 11 frequencies with SNR > 5, respectively. The red solid line in the bottom panel corresponds to five times the noise spectrum.
