2D histograms close to the focusing region of pitch angle (x − axis, from 0° to 180° with one tick equalling 45°) and magnetic field azimuthal angle (y − axis, from −180° to 180°) in the same format as Fig. C.1 with the exception, that pairs of histograms individually filtered by the velocity of the primary (P) or the secondary (S) ISN trajectory are shown for each combination of ϖ_inj, P/ ϖ_inj, S and ecliptic latitudes around the focusing cone.
