Web13 de jan. de 2004 · We use the two test functions that are plotted in Fig. 5. The first function is a sinusoidal signal, f i = 0.1 sin (2πt i /3), that is a curve resembling the shape for an eclipsing binary star. The period, 3 days, is typical for stars in the data set and we also match the irregular time sampling based on brightness data from observed data.
