GLS periodogram of the joint V -band LCOGT Teide and Haleakal = a light curve. The horizontal lines mark the theoretical FAP levels of 1% (dotted), 5% (dash-dotted), and 10% (dashed). The highest peak, near the 10% FAP level, which is related to the rotational period and has a period of 26.0 ± 2.5 d, and the signal found in the RV data at ~19 d are marked with blue vertical bands.
