a) Angular distribution function of accelerated upstream electrons with energy of 3 keV for a wavy shock with θ_B = 85° in an arbitrarily chosen upstream point (thin solid line). The figure complements the previous Fig. 10. The thick line shows the distribution of reflected electrons at a smoothed shock wave with θ_Bn = θ_B. The shock front is located in the direction of B₁. b) The same as in a), but the thin solid line shows the angular distribution averaged along the shock front.
