Radial position (r), heliographic longitude (ϕ) and pitch angle (α) of a 300 MeV proton for the first 5 min of propagation under two different scattering conditions. The left column is for a scatter-free simulation, and the right column is for a proton from a simulation with a scattering mean free path of λ = 0.1 AU. Both simulations had injection at r_i = 20 R_⊙. Two scattering events occur in the right hand side panels at ∼3.5 and ∼4 min.
