Caption: Figure 2.

Relative astrometry of WISPIT 2c to the primary star over time. We give the separation and position angle (measured from north over east). The purple dashed line indicates plausible orbital motion for a prograde orbit, while the blue dashed line indicates retrograde motion. Both orbits are in the plane of the circumstellar disk. The solid curved line indicates the expected behavior for a distant background object, while the black dashed line represents no relative change of motion in relation to the host star.
