Proper motions were determined for 2169 stars with limiting magnitude B = 16.5 mag and located within a 60x60' area centered at RA = 23h54.2min, Dec = 60deg57arcmin (1950.0)....

已对位于以赤经（Right Ascension, RA）23时54.2分、赤纬（Declination, Dec）60°57′（历元1950.0）为中心的60′×60′天区内，且B波段极限星等为16.5星等的2169颗恒星测定了自行（Proper motions）。……
