Left panel: sample trajectories computed over the duration of one simulation for 70 MeV protons in a magnetic field for which (δB/B₀) = 0.48, with B₀ = 0.1 nT. The red line corresponds to a purely transverse turbulent component, while ﹩{(\delta {B}_{z}/\delta B)}^{2}=95 \% ﹩ for the blue line. Right panel: a small portion of the trajectory of a 70 MeV proton in the presence of a field statistically identical to that assumed in the left panel, but with all variance allocated to the compressive component. The total parallel displacement of the proton in the presence of the latter field extends to several thousand astronomical units (see Figure 6).
