Upper panels: nodal (panel 1) and apsidal precession (panel 3) angles as well as inclination angles (panel 2) of a test particle experiencing the gravitational field of a disc and central star only. The solid lines show the results when viewed in a frame in which the disc is assumed to be coplanar with the reference plane. The dashed lines show the same quantities for the same model, but where the disc is now treated as if it was inclined by γF = 0.78(45°) to the reference plane, as it will be when the binary companion is included. Middle panels: nodal (dashed lines) and apsidal (solid lines) precession rates when the disc is highly inclined as a function of semi-major axis ai (panel 4), eccentricity ei (panel 5) and relative inclination δi (panel 6) for a standard disc mass (black) and a disc with the double mass (red). Bottom panels: nodal (dashed) and apsidal (solid) precession rates caused by the highly inclined disc as a function of semi-major axis ai (panel 7), eccentricity ei (panel 8) and relative inclination δi (panel 9) for a standard disc mass (black) and a disc with double that mass (red). In panel 7 a polynomial fit to the apsidal precession rates is shown (dotted lines).
