Heliographic latitude () and longitude (ϕ_cross) of the locations where energetic protons reach the solar surface for simulations with; an 8° ×8° injection region (centred at 0°, 0°) at r_i = 20 R_⊙ and λ = 0.1 AU (panels a and c) and 0.01 AU (panels b and d). Panels a and b: are for a 300 MeV mono-energetic proton population, while c and d are for a 1 GeV population. The red box denotes the region on the solar surface that maps to the injection region. All panels are displaying −40 to 30° in latitude and −25 to 45° in longitude. The crossing positions of the 1 GeV simulations extend beyond these limits with particles in the λ = 0.01 AU simulation crossing 1 R_⊙ between −82.5 to 97.6° in longitude and between −79.1 and 67.3° in latitude.
