Energy spectra of the SWI (black dashed line) and PUI (black solid line) components integrated into the downstream region (X − X_sh = 0 to 1000λ_i) at Ω_ciT = 500. The energy is normalized by ﹩{E}_{A}=0.5{m}_{i}{v}_{A}^{2}﹩. The orange dashed line corresponds to a power-law distribution with a power-law index of −2.2. The blue dashed line is a kappa distribution. The kappa index κ is 4.5, and the downstream ion temperature T_d is ﹩5.25{m}_{i}{v}_{A}^{2}﹩.
