Orbit fit for HD 212330/TIC 259291108 using the astrometric data from S. R. Kane et al. (2019) at epoch 2017.4 and A. Tokovinin (2023) at epoch 2022.4, which are shown as purple diamonds, and the radial velocity fit from S. R. Kane et al. (2019). The black line represents the best fit, while the gray lines represent possible solutions within 2σ. The right panels show the separation and position angle of the orbit as a function of epoch. The × symbol shows the predicted position of the stellar companion at the time of the 2020 Zorro observations, which is consistent with our fit to the data.
