Analytical precession rates calculated from equation (2.32) of Farago & Laskar (2010) as a function of disc inclination, for the cases of the polar-aligning discs in Section 4.1 (top) and the GW Ori system in Section 4.2 (bottom). The vertical line denotes the critical inclination |$i_{\rm crit}$| for this system; inclinations lower than |$i_{\rm crit}$| align to a coplanar orientation, while inclinations higher than |$i_{\rm crit}$| align to a polar orientation. Precession rates are normalized to |$T_0$|⁠, the precession rate for a nearly coplanar or nearly polar disc.
