The correlation of the deviation value of the Gaussian distribution vs the energy spectral index. The triangles represent the total energy spectral index in each case. The circles indicate the subshock’s energy spectral index in each case. From Cases A to D, all of the values of the subshock’s energy spectral index Γ_sub > 1 show a slightly harder power-law slope in the respective order. From Cases A to D, all of the values of the total energy spectral index Γ_tot < 1 show a slightly decreasing deviation from the power-law slope in the respective energy spectrum.
