(a) Ionization volume and coordinate system defined for the simulations (not to scale). OA, ion emission direction; OB, projection of OA on the - plane; , elevation angle; , azimuth angle. (b) Ion trajectories starting from the point (, , ) = (−0.5, 1.5, 0.5). (c) Expansion of (b) near the starting points of the ion flights.
