HARPS (filled symbols) and ESPaDOnS (open symbols) He i radial velocity measurements, with respective error bars. The red curves represent the best-fit hot-spot model for the He i radial velocity data obtained with i = 60° (solid line) and i = 45° (dashed line). The black solid line corresponds to the best fit to the veiling variations with i = 60°, presented in Fig. 5.
