Figure 3

DMSP F18 particle observations along the passage from the dusk to the prenoon sector. The top panel indicates the electron and ion integral energy fluxes, and the second panel shows the average energy. The bottom two panels present the electron and ion differential energy flux spectrograms. The red horizontal bar, which extends from 75.50° to 72.54° MLAT, indicates the region we defined as the cusp.
