"The `IsolatedStarStellarMotions` table provides calibrated positions, proper motions, and parallaxes for isolated point sources across the survey footprint. Following single-frame processing, point sources with no nearby neighbors within a $2^{\\prime\\prime}$ radius are identified across all input science images. These isolated sources are cross-matched across multiple overlapping visits and tied to an external reference catalog (Gaia DR3). The global astrometric model is computed jointly across the matched visits using `gbdesAstrometricFitTask`. Each distinct physical star in this catalog is tracked across visits by a unique identifier, `isolated_star_id`.\n",
