Best-fit hot spot model for the HARPS veiling variations (black lines). The red lines represent the veiling generated by the optimal hot spot fits to the He i radial velocity variations (Fig. 6). Models with i = 60° and i = 45° are shown as solid and dashed lines, respectively . The mean error bar in the observed veiling is shown on the left and the color code of the points is the same as in Fig. 1.
