a) Angular distribution function of accelerated downstream electrons with energy of 3 keV for a wavy shock with θ_B = 85° in an arbitrarily chosen downstream point (thin solid line). The layout is similar to Fig. 9. The thick line shows the distribution of transmitted electrons through a smoothed shock wave with θ_Bn = θ_B. b) The same as in a), but the thin solid line shows the angular distribution averaged along the shock front.
