3D visualisation of the F_long and F_tran wave-energy fluxes at t = 40 min. The magnetic field structure previously presented in Fig. 1, is now shown in grey. Semi-opaque isosurfaces highlight the wave-energy fluxes at 3 kWm⁻² in each reconstructed frequency range; less than 2.5 mHz (red), between 2.5 mHz and 5 mHz (orange), between 5 mHz and 10 mHz (green), and greater than 10 mHz (cyan). The white opaque surface represents plasma β equal to one.
