Selected 56 macropixels overlaid on a representative IBEX-Hi ENA map for reference. The color-coding of the pixel boundaries indicates the degree of confidence in the derived HP distances, as described in Section 3.5. Green indicates category 1 pixels, where the best-fit time correlation coefficient is greater than 0.75; blue indicates category 2 pixels (correlation coefficient between 0.25 and 0.75); orange indicates category 3 pixels (tailward pixels); and red indicates category 4 pixels (see text). The upwind direction (“nose”) and the locations in the sky of Voyagers 1 and 2 (“V1” and “V2”) are also called out.
