Relative change in the season-integrated flux (solid lines), density at the ecliptic longitude where the NIS gas flow intersects the Earth’s orbit (broken lines), and time-dependent survival probabilities of the NIS atoms reaching IBEX at this location (dotted lines). All quantities are shown as ratios to the respective values in 2009. The relative change in the flux is equivalent to the change of total counts per orbit. The color code for species is indicated in the panel.
