Anisotropic KHM results, labelled iso-contours of different quantities as a function of the separation scales l and l (averaged over the time period 200 ≤ tΩi ≤ 300): (a) Second-order structure function S, (b) Decay rate ∂tS, (c) MHD cascade rate KMHD, (d) Hall cascade rate KHall, (e) pressure–strain (effective dissipation) term Ψ, and (f) resistive dissipation term D. The dotted line in panel a displays a circle as a measure of anisotropy. The dotted lines in panel c denote non-positive values. The KHM quantities are normalised to the (time-averaged) effective total dissipation rate Q.
