Spectral transfer analysis, the validity test of the isotropic ST O_k, Eq. (A.7), as a function of k (averaged over the time interval 200 ≤ tΩ_i ≤ 300) (black line) along with the different contributing terms: decay rate ∂_tE_k (blue), MHD cascade rate S​_MHDk (green), Hall cascade rate S​_Hallk (orange), resistive dissipation rate D_k (red), and pressure–strain rate Ψ_k (magenta). All the quantities are given in units of the total (effective) heating rate Q.
