摘要
以JPL提供的太阳系天体数值历表DE200/LE200和美国海军天文台提供的岁差、章动改正程序为出发点,本文介绍为计算大行星、月球掩源(恒星或射电源)而进行的被掩源初选的一种有效方法。用该法本文给出了1995-2050年各大行星及月球可能掩的FK5星。
Starling with the numerical cphcmcris of the celestial bodies in the solar system, D.E200/ LE200, constructed by JPL, and the routines for the correction of precession and nutation, provided by the United States Naval Observatory, this paper proposes a method of sclecting candidates of occulted stars by the planets and the Moon. And we apply the method to FK5 star catalog.
