I am trying to transport Galactic cosmic rays (GCR) through GPS class in Geant4, by taking the help of example/advanced/radio protection. Normally in the primary.mac file proton spectra I have incorporated like (given below),
/gps/hist/point 0.01 7278296000000
/gps/hist/point 0.01338088 6077616000000
/gps/hist/point 0.01790479 5062866000000
/gps/hist/point 0.02390681 4211867000000
/gps/hist/point 0.03183221 3499588000000
/gps/hist/point 0.04210285 2910817000000
/gps/hist/point 0.05510735 2429454000000
. can I add multiple particle fluxes in different columns in the same file (at the same energy bin/point)?
If someone has an idea of how to include different particle fluxes ( such as proton, oxygen, Fe etc), which comes in GCR. Kindly suggest how to proceed in this case through GPS.
