Parameters for mono-energetic Monte Carlo calculation, depending on GCR or SPE computation. For each energy and Z, 10 iterations of 10,000 particles launched have been performed, leading to a total number of 2.52 × 10⁷ (respectively 1.1 × 10⁶) incident particles for GCR (respectively SPE) computations.
