摘要：

Using the ACT reference catalogue as preliminary reference we have reduced 31 exposures on 15 plates in two areas taken with the 40-cm refractor of our Observatory; Using the central overlapping technique and an iterative procedure we have derived high-precision positions and proper motions for 54 stars, including 16 Hipparcos stars. For the latter, the mean standard errors, in right ascension and declination, are 0.70 and 0.59 mas/yr in proper motion, and 10.5 and 7.5 mas in position.
