Omnidirectional spectral properties of different quantities at tΩ_i = 700: (a) Power spectral densities of (solid) the magnetic field B, P_B (solid), and compensated proton velocity field w, P_w (dashed), as a function of k normalised to d_i. (b) Cross helicity co-spectrum P_Hc (solid) and (absolute value of) kinetic helicity co-spectrum P_Hk (dashed) as a function of k. The dotted lines show a spectrum ∝k^−5/3 for comparison.
