Total downward energy flux as a function of downward characteristic energy in the north. The colors correspond to different time intervals: black is for a time interval when the energy flux contribution from 3-30 keV electrons peaks (see Figs. 5, and S7 to S21), blue (orange) is for times when Juno is polarward (equatorward) of that interval. The black data points also correspond to the minimum of the characteristic energy.
