MFPs of mirroring and scattering particles measured at different CR energies. The initial pitch angle values are set to μ₀∈[0.1,0.2] and μ₀∈[0.8,0.9] for mirroring and scattering particles, respectively. The results in panels a, b, and c are based on the R1, R2, and R3 listed in Table 1, respectively. The different symbols denote the numerical results, and the solid lines are a linear fitting for them. The vertical dash-dotted lines indicate the transition scales. The blue area plotted in each panel represents the dissipation scales estimated by the power spectra of the magnetic field.
