Caption: Fig. 3.

Perturbation orbit of HD 33636 on the sky (line). The open circles represent the HST epoch normal points and are connected to the derived orbit by residual vectors. The HST data cover 20% of the orbit period. The orbital motion direction is indicated by the arrow. The square marks the location of periastron passage, and the next time of occurrence is labeled.
