Fig. 3
Energy-dependent flux as a function of pulse phase for different observation angles iobs = 25°, 50°, and 75°from left to right (see Sect. 3.1 for the geometrical set-up). The pulse profiles are normalized such that for every energy bin the mean flux is zero and the corresponding standard deviation is unity (after Ferrigno et al. 2011). The pulse profiles are plotted twice for clarity.
