Is the solar 5 min oscillation an important heating mechanism for the chromosphere and the corona?

Missing power in the spectrum of intensity fluctuations of both XUV and radio emission in the transition layer and inner corona as well as the 90° phase shift between intensity and velocity fluctuations in the chromosphere indicate that the 5 min oscillation transports little energy and is not a significant mechanical heat source for the chromosphere and possibly not even for the corona.
