Although we can use $\Omega_f$, $\omega_f$ and $i_f$ as observables now, astrometric solutions might provide instead the Thiele-Innes constants.
$$A = a (\cos\Omega \cos\omega − \sin\Omega \sin\omega\cos i)$$
$$B = a (\sin\Omega \cos\omega + \cos\Omega \sin\omega\cos i)$$
$$F = a (-\cos\Omega \sin\omega + \sin\Omega \cos\omega\cos i)$$
$$G = a (-\sin\Omega \sin\omega + \cos\Omega \cos\omega\cos i)$$
It would be good to provide these as options.
