Description: IAU 的标准基本天文程序库SOFA 给出Fortran 版和C 版两个基本天文运算的库函数，最新版SOFA 补充了IAU 在2006 年公布的岁差模型。SOFA 由两部分组成：天文库和矢量、矩阵运算库。其中前者有109 个子程序，可以进行天文历法计算、时间计算、星历表计算、岁差章动计算、恒星空间运动计算和主要星表系统的转换，后者有52 个子程序，功能则是矢量和矩阵的各种操作，当然其中包括了球面坐标系统的变换-IAU standard basic astronomical library SOFA Fortran and C version gives two basic astronomical arithmetic library functions, the latest version of the SOFA supplement published in 2006 IAU precession model. SOFA consists of two parts: day library and vector, matrix arithmetic library. There are 109 sub-programs in which the former can be astronomical calendar calculations, calculation of time, ephemeris calculations NUTATION calculated stellar space motion calculation and conversion of major star catalog system, which has 52 sub-program, function is the vector sum a variety of matrix operations, of course, which includes the spherical coordinate system transformation Platform: |
