Scientific paper

This paper gives the precise positions and proper motions of 92 stars of the Chinese Astronomical Almanac, which are not contained in FK5. Their precisions are no longer satisfied. So the positions and proper motions of those 92 stars were determined by using 39 catalogues in FK5 system. The accuracies of the final results are evaluated. The mean standard errors of 92 stars are 0″066 and 0″067 for right ascension and declination at mean epoch, 0″215 and 0″218 per century for proper motion respectively.
