Left panel: phase-folded diagram of IRD_HK. Middle panel: IRD_Hα. Right panel: time series of the CCFc measurements. The planetary inferior conjunction is at φ = 0. Colors (online version only) and numbers are the same as in the previous figures. In the left and middle panel, the gray dashed line is the least-squares best fit discussed in the text. We also report in the text the relative likelihood of the sinusoidal fit with respect to the flat model returned by the AICc.
