Caption: Figure 10.

Lomb–Scargle periodograms of the photometric data shown in Figure 9. Top: zoom in on the presumed rotation period, showing several nearby peaks in all three data sets. Bottom: same as the top over a wider period range. Takeaway: multiple closely related periodicities are visible in Fourier space for all three photometric data sets, providing more evidence for differentially rotating active regions.
