    • We tested this approximation by evolving our models with a fully general relativistic hydrodynamics code described in 3844. We verified the existence of close quasiequilibrium orbits that remained stable for over an orbital period for all cases with positive spins and (moderately) negative spins, justifying this approximation.

    • The approximate boundary condition for the scalar potential (Formula presented) (27) was based on the assumption that the stellar surface does not stray drastically from the spherical shape. The deformation from sphericity is at its worst for the closest separation distances (Fig. 66), undermining the validity of this approximation for those cases. However, its use is still justified by the fact that the influence of the field (Formula presented) in the final result is rather small (Table II) and that these orbits are very likely to be inside the ISCO
