Notes. The numberof modulation component from the wavelet analysis (wi ) and the Fourier decomposition (fi) is given. The harmonic relation to other period components, frequency, period, phase with respect to the zero point, the semi-amplitude in parts-per-million and milli-magnitudes are reported. The final column gives the signal-to-noise of the frequency, which was computed for each oscillation mode within a frequency box of 0.1 c/d.
