Top: radial velocities measured with the HIRES and HARPS spectrographs. The data are period-folded on the best-fit transit ephemeris, the 0 of the x-axis corresponding to the inferior conjunction time. The fit is superimposed on red and the respective residuals are shown on the bottom panel. The left panels display those corresponding data during the whole planetary orbit and the right ones are a zoom on the box to highlight the (undetected) Rossiter-McLaughlin effect. The HARPS binned data are added in black diamonds filled white for clarity.
