Proper motions of open clusters from UCAC4

We present a catalog of mean proper motions and membership probabilities of individual stars for optically visible open clusters, which have been determined using data from the...本研究构建了一份针对光学可见疏散星团（optically visible open clusters）的单颗恒星平均自行（proper motion）与成员星概率（membership probability）星表，相关参数均基于……的数据测定得到。
