Relative proper motions in right ascension (left) and declination (right) for the 144 members of the Bermuda cluster selected in Villafranca II as a function of the difference in each coordinate with respect to the cluster center. Red symbols are used for the 17 brightest systems in G′ and black symbols for the 127 fainter systems. The corresponding separation and velocity scales are given in the top and right axes, respectively. The correlation factors for the bright and faint systems are also given. The region in gray shows the possible linear fits to the faint systems in each case after rejecting outliers to leave 104 objects (left) and 107 (right).
