Interplay between the flow parameters: Top: an extremely solid measurement of IBEX-Lo is the Earth longitude of the maximum neutral atom flux λE, where the entrance field (hatched cones) is directed against the flow (≃ortho-radial bulk flow). Each value of λE corresponds to a continuum of pairs of flow longitude and speed values, as illustrated by the two (black and red) trajectories. Bottom left: the corresponding longitude-speed relationship inferred by Möbius et al. (2012) (black line) and based on the measurement of λE with IBEX-Lo. Also shown is the central part of the chi-square parametric image of Bzowski et al. (2012), which also corresponds to the same longitude-speed link. The consensus pair of values is fully compatible with those relationships. Bottom right: the temperature-longitude derived by Möbius et al. (2012) based on the flux measurements during the rotation around the IBEX spin axis. The authors considered both the absence (top curve) and the presence (bottom curve) of high rate suppression of events (or dead-time). The consensus temperature of ≃6300 K is compatible with the consensus flow longitude of ≃75.4° for a dead-time on the order of 5 ms or slightly higher, i.e., realistic values according to Möbius et al. (2012).
