摘要
使用上海天文台佘山40cm折射望远镜拍摄的底片资料,对球状星团M79中心附近15’×15’天区内106颗恒星和63颗Tycho-2星,以《Tycho-2星表》中M79附近1°×1°天区内上述63颗Ty cho-2星的位置和自行为参考,归算得到了所有169颗恒星的位置和自行,并估计了其成员概率。
From the plates taken with the 40 cm refractor at Sheshan station of Shanghai Astronomical Observatory, the positions and proper motions of 169 stars in the globular clusters M79 region are found, referred to the positions and proper motions of 63 stars in the region which can be found in the Tycho-2 Catalogue, and their membership probabilities are estimated.
