摘要
整理汇集了迄今最完整的同时具备绝对自行与视向速度数据的 14 4个疏散星团样本 ,计算得出这些星团的 3维空间速度。对银河系疏散星团的空间分布 (采用了更多样本 )
An updated, most complete catalogue of open clusters with both absolute proper motion and radial velocity data available compiled and the 3D velocities for each open cluster relative to the GSR are derived. Some statistical analyses concerning spatial distribution as well as kinematical properties of Galactic open clusters are also made briefly.
