Notes. Second column: expected ratio between disc radii and separation as predicted by Artymowicz & Lubow (1994) when assuming circular orbits (e = 0). Third column: observed ratio between disc radii R95,gas and projected separation. Fourth column: minimum eccentricities of the orbits estimated assuming zero orbital inclination and physical separation a between the components that matches the projected separation ap. Agreement with analytical model with zero eccentricity(†) within one sigma;(*) within 1.5 sigmas;(‡) within 3.5 sigmas (see Fig. 14).
