Relations between the mapped DC Poynting flux (< 0.125 Hz) and the mapped outflowing ion number flux in the SZA ranges of a 45°–85°, b 65°–105°, c 85°–125°, d 105°–145°, and e 45°–145° (all events), and f comparisons among the derived empirical relations in these SZA ranges and the empirical formula derived by Strangeway et al. (2005) (their Eq. 5) (multiplied by a factor of 2.9 to correct for the altitudinal difference of the ion number flux and the DC Poynting flux) (dotted gray line). The format of Fig. 5a–5e is identical to that of Fig. 3a–3d. In Fig. 5f, the empirical relations in the SZA ranges of 45°–145° (all data) are shown using a thick black line, in addition to the format of Fig. 3e
