Phase-plots using the rotation frequency f_rot = 1.114997   d^-1. Upper left: the subset of CoRoT data averaged over the HARPS integration times when simultaneous spectroscopy is available. The cycle-to-cycle variations are due to the dominant pulsation modes. Upper right: the EW; lower panels:  ⟨ v ⟩  and  ⟨ v² ⟩  of the He i line at 6678 Å. The small symbols are observations, while the larger red circles are phase-binned averages.
