Scatter plots of the average velocity (panel a), maximum velocity (panel b), and the CME velocity at SEP peak flux (panel c) vs SEP peak flux in the > 10 MeV (red), > 50 MeV (blue), and > 100 MeV (green) energy channels. The open symbols represent disk events (longitude −20 < L < 45) and the filled symbols represent west events (longitude > 45) and vertical lines represent east events (longitude < −20).
