As Fig. 9 but for a binary matching the binary in our SPH simulations. The dashed line give the Leung & Lee (2013) prescription for the precession rates given in equation (3), and the red circle is the measured rate from our simulations (values taken from Fig. 5). We find good agreement between our SPH precession rate and that predicted by Leung & Lee (2013), consistent with the uncertainty from the test particle runs.
