Calculating galactic space velocities and their uncertainties, with an application to the Ursa Major group
Abstract
Formulas are presented for calculating a star's Galactic space-velocity components U, V, and W from its proper motion, parallax, and radial velocity. The authors also show how to calculate σU, σV, and σW from the uncertainties in the observational quantities. As an example, space velocities are calculated for solar-type stars in the Ursa Major Group, which are then compared to A stars in the nucleus of this cluster and to the broader "supercluster".

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
