Results of the energy transfer analysis. Panel a: Magnetic energy transfer as a function of the normalized wavenumber with k_R = 2π/R_* averaged over twenty spectra spanning three orbital periods during the saturated phase, 137 ≤ t/P_orb ≤ 140. Positive values of transfer functions at a given wavenumber k (full line) indicate gain of energy at the scale 2π/k, negative values (dashed line) indicate a loss of energy at this scale. Panel b: Same as panel a, except splitting the magnetic energy transfer rate into magnetic cascade contribution T_MA(k)+0.5T_MC(k) and kinetic to magnetic energy transfer T_MT(k)+0.5T_MC(k).
