Neutron and proton fluxes in the atmosphere

This table contains the neutron and proton fluxes in the atmosphere calculated by Monte Carlo Method.
The details of the calculations are given in:

Latitude

             Latitude                 Neutron Flux              Proton Flux
             Degrees                  [MeV-1 s-1 cm-2]  [MeV-1 s-1 cm-2]
              0-10                        n10.0                       p10.0
            10-20                        n20.0                       p20.0
                                            .......
            70-90                        n90.0                       p20.0
All fluxes are normalized per unit depth.
