Density map of the depth of the primary eclipse versus the depth of the deepest Gaussian. The sample of sources whose light curves are modelled with two Gaussians and without an ellipsoidal component is shown in the top panel, while those with two Gaussians and a cosine function are shown in the bottom panel. The density in the maps is colour coded according to the colour scales shown to the right of each panel. The axes ranges have been restricted for better visibility.
