天王星卫星CCD观测的初步分析

１９９５ 年８ 月在上海天文台利用安装在１ ．５６ 米望远镜上的ＣＣＤ 探测器对天王星五颗主要卫星进行了定位试观测。将观测所得的位置资料与其理论值做了比较。结果表明：ＣＣＤ观测的位置精度优于照相观测的结果。这些资料对于卫星轨道的研究是有价值的。

A PRELIMINARY ANALYSIS ON CCD ASTROMETRY OF URANIAN SATELLITES

The major satellites of Uranus were observed with the CCD detector equipped on the 1.56m telescope at the Shanghai Astronomical Observation during the 1995 opposition. These observed positions were compared with those calculated theoretically. The result has shown that the precessions of the data obtained using the CCD detector are better than those obtained using the photographic plates. Therefore these observations are valuable to the investigation of the orbits of the Uranian satellites.
