Caption: Figure 2.
(a) Differential energy spectra of 0.5–6 keV ENAs observed by IBEX-Hi along the lines of sight (LOS's) of the two Voyager spacecraft. Dotted curves: measurements in IBEX frame; solid curves: measurements in solar inertial frame. (b) Energy dependence of the ENA spectral index in the solar inertial frame along V1 and V2.
