Summed spin phase-time histogram of data of energy bin 3 recorded by IBEX-Lo during orbit 65. The spin phase is the heliospheric latitude in spacecraft coordinates with the ecliptic plane being at spin phase of 0.75 (see text for details). The interstellar wind signal can be seen as a wide horizontal strip across the figure between 0.69 and 0.80 in spin phase, which is almost aligned with the ecliptic plane at spin phase 0.75. The right panel shows a histogram for the time period.
