Final proper-motion distributions for CDDS stars in Praesepe (upper panel, 160 stars) and the Pleiades (lower panel, 151 stars). Data for each cluster are centered on the median proper motion from J. Alfonso & A. García-Varela (2023): (μR.A., μdecl.) = (19.95, −45.44) for the Pleiades and (−35.93, −12.88) for Praesepe. The density of members increases from low (black points) to medium (gold points) to high (bright yellow points).
