LSD Stokes V (upper-left panel), Stokes I (lower-left panel), and Lomb-Scargle periodograms for two different TESS sectors (right panel) for the various stars in our sample, arranged by stellar identifier. For stars with a large amount of low-frequency amplitude the lightcurves were pre-whitened, removing low-frequency high-amplitude peaks, resulting in the before (grey) and after (black) periodograms. In each case, the x-axis extends to cover the highest frequency signals found in the data. The red curve is a 5-term fit to the rotation frequency (cont.).
