Left: densities of the thermal ions (blue), transmitted pickup ions (orange dashed), and injected pickup ions (green) as functions of radial distance r. The total ion density is plotted as the black line. Right: density ratios between transmitted pickup ions and thermal ions n_tp/n_th (blue dashed), between transmitted pickup ions and total ions n_tp/n_i (orange), and between injected pickup ions and total ions n_inj/n_i (green).
