GLS periodograms of the RV data (green line) and the GLS of the residuals(blue line) after subtracting the best model of the RV stellar activity (P_rot = 35.23 ± 0.11 days) and the Keplerian signal (19.466 ± 0.005 days) at the same time. The horizontal dashed lines indicate FAP levels of 10% (blue), 1% (orange), and 0.1% (green). The black and red vertical dashed lines indicate the orbital rotational period of the planet and the rotation period of the star, respectively.
