Table A2
χ2 and |RD| values for different models (ARAMIS, GEANT4 & PHITS Matthia, OLTARIS) of Martian surface flux from 15 November 2015 to 15 January 2016 using FTFP_INCLXX_HP, for (a) neutron, (b) photon and (c) proton. The OLTARIS model provides only direction averaged flux, so for charged particles the χ2 and |RD| are not included.
