Number of extracted independent sinusoids (n – n_h) versus the input number of sinusoids put into the light curve (n_input). Harmonic sinusoids are filtered out as they capture residuals related to the eclipse model that are unrelated to the number of input sinusoids. Points are divided into month-long time series (blue) and year-long time series (orange), and the error bars are calculated as the square root of the number n – n_h.
