Abstract
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.
