Characteristic energy (a) and (b) and energy flux (c) and (d) projected onto false color images of the north (left) and south (right). Panel (e) and (f) show the bare images with tracks. The false color images were collected for 40-60 minutes around the main oval crossing. There is a good agreement between the reddish (greenish) color of the images with the higher (lower) values of the characteristic energy. The area where the bars in panels (a)-(d) are narrower and where the boxes are shown in the bare images (e) and (f) correspond to the region where the 3-30 keV electron energy flux contribution to the total energy flux peaks (See also Table 1 and Figs. 5 and 6).
