Table A1

GCR spectrum parameters specify the energy range responsible for 98% of absorbed dose rate in each phantom. For each GCR species, as indicated in the first column, the energy range is specified for solar minimum (ϕ = 400 MV) and solar maximum (ϕ = 1500 MV). The CRaTER-Al column represents the microdosimeter with 5 mm shielding. Note that E 1% is in MeV, while E 99% is in GeV. The E 99% energies have been up-rounded and the E 1% have been truncated. To cover both solar minimum and maximum, the simulator should use E 1% (ϕ = 400 MV) and E 99% (ϕ = 1500 MV).
