Effect of downstream cross-field diffusion strength a_⊥ = 0.1 on the injection efficiency for V_s = 1500   km   s^-1, κ = 2, and different shock-normal angles. Curves (from numerical integration results) and results from simulations without cross-field diffusion (squares) are the same as in Fig. 6. Results for the two types of downstream cross-field diffusion (sets three and four) are shown as triangles and diamonds.
