Caption: Figure 9.
Performance of the kinegeometric velocity estimate (median of the posterior) as a function of distance for the constant fraction sample in the mock catalog. The left panel shows the bias in the estimates. The right panel shows the scatter. The color scale shows the density of stars on a log scale. The solid orange line shows the median bias or scatter at each distance; the dotted lines the 5th and 95th percentiles. The blue lines show the same metrics for the geometric method (geometric distance times proper motion).
