\caption{\label{fit} The remaining orbital elements $i$ and $\Omega$ for HD~38529 and
HD~168443, as obtained from our astrometric fit using the Hipparcos Intermediate
Astrometric Data. Corrections to the standard five astrometric parameters in
Hipparcos, derived from the same fit, are also given, as well as the derived
companion masses based on our best fit inclinations.}
