Bayesian periodograms of various stellar activity indicators of Gl 382. From left to right and top to bottom the Ca II IRT 1, 2, 3, dLW, Hα, and NaD1 index time series from the CARMENES data; the dLW, Hα, and NaD1 index time series from the HARPS data; and the dLW, Bℓ, and dET time series from the SPIRou data. The dashed green lines in the bottom panel mark periodicities at the stellar rotation period (P_rot), at the one-half rotation period (P_rot/2), and at 51.1 d. The significance level of log BF = 5 is indicated by the horizontal red dashed line.
