Copyright (C) 2013-2014, NumFOCUS Foundation. All rights reserved. This library is derived, with permission, from the International Astronomical Union's "Standards of Fundamental Astronomy" library, available from http://www.iausofa.org. The ERFA version is intended to retain identical functionality to the SOFA library, but made distinct through different function and file names, as set out in the SOFA license conditions. The SOFA original has a role as a reference standard for the IAU and IERS, and consequently redistribution is permitted only in its unaltered state. The ERFA version is not subject to this restriction and therefore can be included in distributions which do not support the concept of "read only" software. Although the intent is to replicate the SOFA API (other than replacement of prefix names) and results (with the exception of bugs; any that are discovered will be fixed), SOFA is not responsible for any errors found in this version of the library. If you wish to acknowledge the SOFA heritage, please acknowledge that you are using a library derived from SOFA, rather than SOFA itself.
