Examples of TESS light curve (left) and Lomb-Scargle periodograms (right). Upper row: HIP 490, a single star from the F150 sample with a single peak in the periodogram. Middle row: HIP 26369, a normally rotating binary with two distinguishable peaks in the periodogram that can be attributed to the two components. Lower row: HIP 2729, a fast rotator binary with two distinguishable peaks in the periodogram that can be attributed to the two components; the other peaks seen in the periodogram are due to the harmonics of these two periods.
