The subprograms are supported by 55 vector/matrix routines.\n\nThis program is derived from the International Astronomical Union's\nSOFA (Standards of Fundamental Astronomy) software collection.\nhttp://www.iausofa.org\n\nThe WWA code does not itself constitute software provided by and/or endorsed by SOFA.\nThis version is intended to retain identical functionality to the SOFA library, but\nmade distinct through different function names (prefixes) and C# language specific\nmodifications in code.\n\nWWA is also available as a NuGet package (WWA \u0026 WWA.Core).\n\nContributor\nAttila Abrudán\nIf you make income with the help of this library please donate to the contributor (help to keep up to date the C# version).\nSOFA Software License\nNOTICE TO USER:\n\nBY USING THIS SOFTWARE YOU ACCEPT THE FOLLOWING SIX TERMS AND\nCONDITIONS WHICH APPLY TO ITS USE.\n\n1.
