Schematic illustration of the secular precessions for a mid inclined orbit relative to the equatorial plane of the black hole. When we have ${\mathbf{z}}_{\mathrm{bh}}=-{\mathbf{y}}_{\mathrm{orb}}^{\mathrm{pro}}+{\mathbf{z}}_{\mathrm{orb}}^{\mathrm{pro}}={\mathbf{y}}_{\mathrm{orb}}^{\mathrm{ret}}-{\mathbf{z}}_{\mathrm{orb}}^{\mathrm{ret}}$ for example, the in-plane precessions act in the same way as for equatorial orbits (see Fig. 6). As for the out-of-plane precessions, the LT precession pushes the apocenter in the same direction as the spin, and the quadrupole moment effect as well for the retrograde orbit but in the direction opposite to the the spin for the prograde orbit.
