Overview plot for event #9 and 10. a) The flux vs. time of electrons travelling outward from the Sun observed by WIND/3DP on December 12, 2002. The labels indicate the channel center energies. b) The flux-time profile of the outward traveling electrons at 108 keV. c) The ion spectrogram of 1/speed vs. arrival time for 10−70 amu ions measured by ACE/ULEIS on December 12−13, 2002. d) The velocity dispersion analysis of the observed times of the electron peak flux at energies above 25 keV for event #10. e) The same analysis, but for the onset times of carbon and heavier ions. f) The electron energy spectrum of background-subtracted peak flux for event #10. In d)−e), the straight lines represent the least-squares fit to the data points.
