Histograms of the longitudes (blue histogram) and absolute values of the latitudes (yellow histogram), respectively, of the current sheet normals, where the longitudes were constrained to lie between 135° and 315° for definitiveness, guided by the observation that the most probable HCS normal at 1 AU would be the ortho-Parker longitude (225°); all longitudes outside of this range were mapped into it by the addition of 180°. Notice that the latitude is binned in equal increments of solid angle.
