Comparison of observed positions of GJ 1245AC with positions expected from orbital elements of Harrington (1990) for the same epochs of observation. Filled circles represent the observed locations of the components. The primary star, GJ 1245A, is located at the origin of the coordinates. Open circles represent the positions computed from the orbital elements. The uncertainties of our positions are ±0﹩\farcs﹩01–0﹩\farcs﹩02 in each coordinate, i.e., much smaller than the radii of the filled circles. The ellipse traces the published orbit of GJ 1245C relative to GJ 1245A. The arrow represents the direction of motion.
