Overall proper motion and transverse velocity as a function of distance for the previously known members and new disk-bearing YSOs of the Lupus, UCL, and US groups. The data points denote the median values for each distance slice and the error bars corresponds to the respective median absolute deviation; the black data points correspond to values for the new disk-bearing YSOs in Lupus or UCL, while the orange data points correspond to values for the new disk-bearing YSOs in US. Each panel shows the corresponding median absolute deviation for known members for Lupus, US, and UCL (shaded bands). The dotted line in the bottom right panel corresponds to a linear fit to the transverse velocity over distance for the new YSO Lupus/UCL members: V_T = 20 ± 1 km s⁻¹.
