Examples of normalized synthetic light curves of dark companion (top panel), semidetached (middle panel), and contact binary systems (bottom panel). Each panel contains three subplots showing different light curve realizations of the system characterized by the mass ratio q and inclination i specified at the top of the panel. The solid black lines represent the noise-free light curves of the systems, while the colored lines show the light curves perturbed with noise. All noisy light curves were injected with uncorrelated Gaussian noise with a standard deviation σ_WN = 10⁻² mag and correlated Gaussian noise modeled using the ExpSineSquared kernel with a standard deviation σ_CN = 0.05 of the unperturbed light curve amplitude (given at the top of each panel) and correlation length scale l_CN = 0.25 of the orbital period.
