Notes. The differences are the values of this work minus literature presented in mas yr-1. The quantities D and their errors are presented in the sixth and seventh columns. This value gives the average of the differences in the μαcosδ and the μδ components for each cluster, which are weighted by the formal errors. See the text for details. The last two columns give the number of common clusters and the catalog being compared, respectively.
