Upper panels: Mean square displacement of the parallel (left) and perpendicular (right) diffusion of the initially mirroring and scattering particles vs. the time (normalized by Ω) for the Alfvén (A), fast (F), and slow (S) modes. Lower panels: Ratio of the parallel (left) to perpendicular (right) mean square displacement between their three plasma modes. The subscripts i and j represent any two of Alfvén, fast, and slow modes. The simulations with the Larmor radius of R_g = 0.03L_inj are based on the decomposed R1 data. The μ values for initially mirroring and scattering particles are set to μ₀∈[0.1,0.2] and μ₀∈[0.8,0.9], respectively.
