  • Average cross-power spectrum of 200 subseries of 4 days each. The spectrum is dominated by the p-mode band up to the cut-off frequency (~5.3 mHz). Above this frequency a mode-like structure appears, corresponding to the so-called High Interference Peaks [HIPs], observed for the first time with unimaged observations (low degree modes) with the GOLF experiment. This has been explained by considering partial wave reflection from the atmosphere:
