摘要
本文得出BD+63°869的相对视差等于0~″.0740±0~″.0126(外部标准差),与其他台站的六次测定结果取平均并改正为绝对视差等于0~″.086±0~″.007.
The trigonometric parallax of BD+63° 869 has been determined from 80 exposures on 29 plates taken during 6 seasons of observation. These plates were measured with the PDS1010MS microdensitometer at Purple Moutain Observatory. A solution of the positions, proper motions and parallaxes for the star BD+63°869 and its reference stars was obtained by means of an iteration procedure of solving the Murray's normal equation in the central overlapping reduction. It gives a relative parallax of 0.″0740±0.″0126 (external standard deviation) for BD+63° 869. The mean of this value and six values of some other observatories, corrected to the absolute parallax, gives a value of 0.″086±0.″007.
