Spatial distribution in the x direction around the shock front and the coupling region of a) B_y; b) gas pressure; c) density; d)v_x; e) v_y; and f) the temperature for the neutral (red) and ionised (blue) fluids at time t = 15 000τ where β = 0.01 and ξ_i = 0.01. The green line indicates the total (pressure and density) or the difference (x and y velocities and temperature) for the two fluids. The plasma pressure and density are increased by a factor of 50 to make their distributions clearly visible. The x-axis has been shifted to set the origin at the shock front.
