Measured long-term modulations (blue) compared to the cycle length included in the simulations in the case of noise-free light curves for the temporal baselines considered in this work, where we retrieve modulations: 4 years (top), 6 years (middle), and 8 years (bottom). The dashed orange line corresponds to the 1:1 line, while the upper dotted orange line and the lower dotted orange line are the 1:1.1 and 1:0.9 lines, respectively. The upper dotted yellow line and the lower dotted yellow line are the 1:1.3 and 1:0.7 lines, respectively.
