                    Model Assumptions:  
                    
                      - Full sky exposure
 
                      - No Galactic Cosmic Ray contributions
 
                      - For fluxes, SEP fluxes assumed
 
                      - Differential energy fluxes are calculated from GOES observations only for near Earth  using inner boundary input into the EPREM model and projected near Mars.
