土星卫星运动的现代理论和CCD观测定标归算

Contemporary Theories of Motion for Saturn's Major Satellites and CCD Calibration

在目前土卫ＣＣＤ观测中，采用亮卫星的理论值定标的方法已被广泛采用，然而如何尽可能减小理论引入的误差对定标的影响仍是一个有待研究的问题．在最新研究中，采用３０００多个最新的ＣＣＤ观测对４个土卫现代理论作实算分析和比较，并由对归算结果的初步分析得出一些有价值的结论．

In the CCD technique in astrometry, the method of bright moons has been in common use in calibration, which suffers from inducing the systematic errors of the brighter moons ephemerides. Minimizing the errors is a problem to be solved. In our recent research the more than 3000 CCD data and the 4 contemporary theories of saturnian satellites were used in calculation for analysis and comparison, some valuable conculations have been given. This paper show a brief description of our study.
