Fig. 3.

Average distribution of flux for 7 selected regions in the near-Mars space, as indicated in Fig. 2. Column 1 shows the position where the sample data ware taken. Column 2 shows H⁺ fluxes, column 3 alpha particle fluxes and column 4 show heavy ion fluxes (O⁺, , ). The colour scale indicates the logarithm of the differential flux [m⁻² s⁻¹ sr⁻¹ eV⁻¹], the x and y axis are logarithmically scaled in eV, but with direction given by the X_MSOR_MSO coordinate system used in Fig. 2, i.e. +X towards the sun, +R outwards from the X axis, away from the planet.
