Astrometric orbit for the eccentric combined solution using Be star RVs (dashed line) with the Be star at the center (star symbol), the line of nodes (gray line), the ascending node (large plus sign), and the periastron position (small plus sign coinciding with the astrometric position on HJD = 60116.6). The relative astrometric positions of the pre-sd star (error ellipses corresponding to 3σ uncertainties) coinciding with the calculated positions on the orbit (x symbols) are shown alongside the average HJD of each observation. For the secondary axes in units of AU, a distance of 296 pc is assumed.
