摘要
使用特纳方法确定了64个天琴座RR变量的相对固有运动。第一个历元位置取自Carte du Ciel星图目录，而第二个历元是用上海天文台Zô-Sè剖面的40厘米折射仪（f=6.9米）在1962年至1965年拍摄的板块测量的位置。这两个时代之间的平均间隔约为60年。本征运动的平均误差为±0.005〃/y。这些变量的绝对本征运动是在校正了视差运动和星系微分旋转后发现的。结果见3个表。
The relative proper motions of 64 RR Lyrae variables are determined using Turner's method. The first-epoch positions are taken from the Carte du Ciel Astrographic Catalogue, while the second-epoch positions are measured positions from plates taken with the 40-cm refractor (f=6.9 m) of the Zô-Sè Section, Shanghai Observatory, in 1962–1965. The average interval between the two epochs is about 60 years. The mean error in the proper motion is ± 0.005″/y.
The absolute proper motions of these variables are found after correcting for the parallactic motions and the galactic differential rotation. The results are given in 3 TABLES.
