Notes. All values are given in rad/day and we assumed ϕl = 1 for both components. Equations come from Liang et al. (2022) and Borkovits et al. (2015). The function ℱ is defined in Eq. (C.8) of Borkovits et al. (2015) and depends on the mutual inclination of orbit A to the outer orbit. Its value is about −0.20 for mutually perpendicular orbits (cos iA, AB = 0) compatible with constraints from Sect. 4.4.
