A Preliminary Study on the Improvement of Proper Motion for HIPPARCOS Stars by using Photographic Plates at Shanghai Observatory
Based on the survey of 3435 photographic plates obtained with the 40 cm astrograph at SheShan section of Shanghai Observatory from 1901 to 1993, four ways to improve the proper motions of about 1000 Hipparcos stars were given, and the final precision of proper motion was also estimated. For example, the proper motions of 32 Hipparcos stars were presented.
