Table A.2

Table of Fourier parameters (frequencies (fj), amplitudes (Aj), and phases (θj)) of peaks with a signal-to-noise ratio (SNR)  ≥ 4, plus clear harmonics () of the main peak at f0 = 0.52687 ± 0.00004   d-1 down to SNR ≥ 3. SNR is calculated over 3   d-1 in the periodogram.

Notes. The group of low-frequency values show up because of noise and not completely removed trends. Several frequencies close to f0 can be explained by the fact that neither the frequency nor the amplitude of f0 is stable, as it can be clearly seen in Fig. 6.
