3D-representation of a “sheet” of particle trajectories with β = 1.0 and Q/m = 0.5 C/kg, during the focusing phase of the solar cycle. The start year is 2000. The “sheet” of particles is started along the Y-axis of the ISD frame. The focusing towards the solar ecliptic plane is visible, but at the same time there is a “defocusing” in the XY-plane (see projection), downstream of the Sun. The color denotes the particle speed in km s^-1.
