Notes. RV differences between clusters and Cepheids are considered significant only if a sufficient number (here: ≳3) of cluster stars was available to determine an accurate median for the cluster. The last column shows apparently highly discrepant values in parentheses if they are based on an insufficient number of stars. References listed in column ‘Refs’ a: Barnes et al.
