Expected signal from the NIS He population for orbits 54 through 59, i.e., from the crossing of the NIS He cone region by IBEX for various lower boundaries of integration of the flux in the IBEX inertial frame over speed. The signal is scaled to the peak flux on orbit 64, identically as in Figure 8, and the vertical scales are also identical. Note that the vertical axis is shifted downward relative to Figure 8. The color coding and axes are identical as in Figure 8.
