Orbital elements for the low inclination case γ_F = 25°. The colours represent planetesimals at different semi-major axes with the convention adopted from Fig. 2. The eccentricity is depicted in panel 1. In panels 2 and 3 the nodal precession and inclination angles are shown, where the short dashed line represents the inner and outer edge of the disc. In panel 4 the relative inclination with respect to the disc is shown, where the short dashed line represents one pressure scale height and the dashed-dotted line indicates where δ_i = α_d. The binary separation D = 60 AU.
