Cluster fits for NGC 2682 for stars within a 0.°35 radius from the cluster center. In pink we show the cluster Gaussian fit to distance (converted from parallax, top), RV (middle), and PM measurements (bottom). In each panel, the mean of the Gaussian cluster fit is marked by a vertical dashed line, and the 10σ bounds are marked by gray vertical lines. A sixth-order polynomial fit to the field-star distance distribution and a Gaussian fit to the field RV measurements are shown by dashed purple lines. In these top two panels, the combined fits are shown by gray curves.
