Encounter 4. From the top we show EPI-Lo ion flux in two look directions, the radial component of the magnetic field, the absolute value of the normalized cross helicity, the normalized deflection, and the anisotropy parameter for the EPI-Lo ions. Two high-z value regions are highlighted and later shown in more detail in Fig. 2. Many instances of polarity reversals of B_R are located outside these regions, but we selected these two in particular for a detailed discussion.
