Comparison of planet trail with predictions of radial velocity anomaly induced by rotation and different wind patterns. Lower panel: planetary trail obtained in the best-fit circular orbit reference frame (same as left panel of Fig. 5, but zooming onto smaller radial velocity displacements from the best-fit circular orbit rest frame), and comparison with predictions of net Doppler shift in different cases: pure rotation (blue dashed curve), east-west wind of 10 km s⁻¹ (green dashed curve), and day-to-night wind of 5 km s⁻¹ (orange dot-dashed curve). Upper panel: contribution to Doppler shift from the portion of the planet disk seen at different phases due to the two wind geometries considered and planet rotation. Black portions of the disk correspond to the night-side, while red(blue) portions correspond to regions producing red(blue)shifted lines. Less weight should be given to phase bins close to quadrature (φ < 0.35; φ > 0.65) because of the detrimental effect of our analysis on the S/N in this phase range (see Fig. 2).
