|Language||Information and source URL's|
|Java||A pure Java translation of the
SOFA software by Dr. Paul Harrison
from the Jodrell Bank Centre for Astrophysics at the University of Manchester, downloadable
|C||Essential Routines for Fundamental
Astronomy (ERFA). This is a copy of the ANSI C version of the SOFA library but with "iau"
removed from all function names and re-licensed to be compatible with typical Free/Open
Source Software licenses (n.b. it is no longer read-only and therefore changes may
be made by anyone). It has been produced by the AstroPy group
(project page) and it may be
downloaded from the GitHub repository:|
|C#||World Wide Astronomy (WWA) library.
This is a set of C# algorithms and procedures that implement standard models used in fundamental
astronomy derived from the SOFA software collection. The WWA library uses different function
names (prefixes) and C# language specific modifications as required by the SOFA license. It
was written by Attila Abrudan and may be downloaded from the Codeplex project hosting site:|
