Total H differential fluxes, J(E), along the V1 (left) and V2 (right) LOSs for simulations A–C. The top panels show the results obtained from the baseline VLISM VDF models, while the bottom panels illustrate the effects of different assumptions for the VLISM (see Table 1). Note that for clarity of visualization, panels (c) and (d) show only the average values. The corresponding time-variability bands are comparable to those shown in panels (a) and (b).
