Density maps of two-Gaussian-related quantities versus ellipsoidal amplitude (peak-to-peak) of the samples 2GE-A (2 A_ell < 0.11) and 2GE-B (2 A_ell ≥ 0.11) of sources with two Gaussians and an ellipsoidal component. Top panel: Primary Gaussian depth, with 1:1 (solid), 2:1 (upper dashed), and 1:2 (lower dashed) lines to guide the eyes. Bottom panel: Secondary-to-primary Gaussian depth ratio. The axis scales are truncated for greater visibility.
