The top panel shows histograms of the standard deviation of RV, U, V and W in binned activity regions, along with the average uncertainty. This plot better highlights the increase in the dispersion of kinematic motion vectors as a function of decreasing chromospheric activity, and hence increase in time. The step up to large dispersion and a flat distribution is seen in all histograms. The lower panel shows the binned totals of the standard deviations for U, V and W space velocities. This allows a clearer picture of the step after the Vaughan-Preston gap region.
