Instantaneous wave-energy flux in slice V1 at t = 350 s. The absolute magnitude of the magnetic flux (upper panel) was calculated in the locations of 3.5 and 5 mHz signals in perpendicular velocity, whilst the acoustic flux (lower panel) was calculated in the locations of 3.5 and 5 mHz signals in pressure. The equipartition level is overlaid as a dashed line. The dotted vertical line represents the partition between case S and case NS.
