GLS periodogram of the ASAS-SN photometry acquired by the camera bd (solid orange) and its window function (dotted grey). The red circle indicates the maximum power frequency. The green dotted vertical line highlights the ≃6.1-day orbital period of HD 118203 b, and the magenta dotted vertical line indicates the ≃ 110-day periodicity found in the ELODIE FWHMs. The horizontal dotted lines correspond to the 10 (orange), 1 (blue), and 0.1 % (green) FAP levels. The right panel illustrates the phase-folded photometry to the maximum power period. The grey data points correspond to a 35-day binning.
