Same as Fig. A.4, but for the sample star EPIC 220652177. Panel (a) shows the K2 C08 light curves obtained from the Kepler archive (blue) and Everest (red). The light curves a clear double-dipping signal. The power spectra in panel (b) were calculated from a PDM (orange, displayed as 1 − θ) and a Lomb-Scargle periodogram (green). The rotation periods identified by RH20 (36.7 d) and us (40.2 d) are both indicated. Panels (c) and (d) show phase-folded plots based on RH20 and our period, respectively. In (a), (c), and (d), we have shifted the Everest data vertically by 0.005 units for visibility reasons.
