Scatter diagrams of the parameters between the ten bump SEE events and the associated solar phenomena, including SXR flares (top), west limb CMEs (middle), and ³He/⁴He (bottom). Panels (a–c): SXR class vs. β, N_pl at 10–400 keV and N_bp at 10–400 keV. Panels (d–e): CME width vs. W_bp/E_bp, N_bp/N_pl at 10–400 keV. Panel (f): CME speed vs. N_bp/N_pl at 10–400 keV. Panels (g–h): ³He/⁴He ratio vs. β and E_bp Panel (i): ³He/⁴He ratio vs. N_bp/N_pl at 10–400 keV. The upward (downward) arrows indicate the underestimated (overestimated) ³He/⁴He ratio. In all panels, blue (red) shows the SEE parameters from the MUL (ADD) fitting. The symbols represent the same as in Figure 2. We used the logarithm of the electron number and of ³He/⁴He ratio to calculate the corresponding CCs.
