Description
The AGK3R and SRS are lists of reference stars containing, respectively, 21,499 stars in the northern hemisphere and 20,500 stars in the southern hemisphere. This paper presents computations of proper motions of these two groups of stars that will permit the use of the observed positions away from the epochs of observation. Tables are presented summarizing the mean errors of AGK3R proper motions and the observational histories of AGK3R and SRS stars.
