<jats:title>Abstract</jats:title><jats:p>Precise radial velocities lately published (Murdoch, Hearnshaw & Clark 1993) allow a simultaneous least-squares adjustment of all visual and spectroscopic observations. Starting with the same data as Murdoch & Hearnshaw (1993), we obtain a mass ratio that agrees better with Kamper & Wesselink’s (1978) astrometric estimate. Our results suggest upward revisions of the distance to the system as well as of the individual masses of the components.</jats:p>
