54             ** Astronomical Union's "Standards of Fundamental Astronomy" library,
55             ** available from http://www.iausofa.org.
56             **
57             ** The ERFA version is intended to retain identical functionality to
58             ** the SOFA library, but made distinct through different function and
59             ** file names, as set out in the SOFA license conditions. The SOFA
60             ** original has a role as a reference standard for the IAU and IERS,
61             ** and consequently redistribution is permitted only in its unaltered
62             ** state. The ERFA version is not subject to this restriction and
63             ** therefore can be included in distributions which do not support the
64             ** concept of "read only" software.
65             **
66             ** Although the intent is to replicate the SOFA API (other than
67             ** replacement of prefix names) and results (with the exception of
68             ** bugs; any that are discovered will be fixed), SOFA is not
69             ** responsible for any errors found in this version of the library.
70             **
71             ** If you wish to acknowledge the SOFA heritage, please acknowledge
72             ** that you are using a library derived from SOFA, rather than SOFA
73             ** itself.
