Notes.We list the seven oscillations in the order of a single high-amplitude frequency (1), two close frequency pairs (2, 3), three overtone frequencies (4, 5, 6), and a low-amplitude frequency (7) whose amplitude matches the 1σ Gaussian noise of the dataset. For every oscillation, we list initial guesses, resulting best-fit values, and actual values for frequency (f), amplitude (A), and phase (δ). To simulate handling a real dataset, we set our starting frequency values to the peak values measured in frequency space. We set starting amplitudes to “reasonable guesses” based on the photometry, and we choose the random phase value 3.0 for all oscillations.
