Figure 5. Particles integrated in Figure 3 but with x-axis being nodal crossing time instead of Ar range, rjj and fi in Figure 5 are essentially still functions of to, apart from the scatter originally generated at ejection time (Figure 4).

The dispersion at subsequent times of particles in a close encounter depends on both the range of elements induced by the encounter and the extent to which subsequent perturbations amplify the scatter. In Figure 5 there was very little such amplification of the scatter in rp and fl, although this may be because only one revolution after 1833 was integrated. The particles removed from the trail were dispersed over a huge distance in the along trail dimension but, initially at least, remain in quite a narrow structure, essentially a separate filament of the stream albeit with very low density because of the along trail dispersion.
