The electron number density n_e along the grey lines denoted in the left panels of Fig. 2 at Ω i 0 t = 15 (black solid line), 17.5 (blue solid line), 20 (green solid line), and 26.5 (red solid line) for run 3. The initial electron density in the inflow region n b = 0.2 n 0 is indicated by the black dashed line in the figure.
