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.

> The IAU Standards Of Fundamental Astronomy Board approves the
