Notes. Columns are (from left to right): The radial height of the shock at particle injection (ri), the parallel scattering mean free path (λ), the number of precipitating protons that reach 1 R⊙ over the full 24 h simulation (Np), the instantaneous precipitation fraction (P), and the percentage of the precipitating protons that reach the solar surface in the first 10 min after injection (F10 min). All simulations injected a 300 MeV mono-energetic proton population consisting of N = 10 million protons into an 8° ×8° injection region.
