本程序是一步一步程序实现一个算法来计算…

本程序根据Jean Meeus的《天文算法》一书中给出的算法，实现对太阳天顶角和方位角的计算，有效时间范围和精度分别为：-2000-6000年，±0.0003 度。 程序作者Ibrahim Reda and Afshin Andreas,由National Renewable Energy Laboratory提供。-This program is a step by step procedure for implementing an algorithm to calculate the solar zenith and azimuth angles in the period from the year-2000 to 6000, with uncertainties of ±0.0003 degree. The algorithm is described in a book written by Jean Meeus in 1998.
