47** This library is derived, with permission, from the International

50**
51** The ERFA version is intended to retain identical functionality to
52** the SOFA library, but made distinct through different function and
53** file names, as set out in the SOFA license conditions. The SOFA
54** original has a role as a reference standard for the IAU and IERS,
55** and consequently redistribution is permitted only in its unaltered
56** state. The ERFA version is not subject to this restriction and
57** therefore can be included in distributions which do not support the
58** concept of "read only" software.
59**
60** Although the intent is to replicate the SOFA API (other than
61** replacement of prefix names) and results (with the exception of
62** bugs; any that are discovered will be fixed), SOFA is not
63** responsible for any errors found in this version of the library.
64**
65** If you wish to acknowledge the SOFA heritage, please acknowledge
66** that you are using a library derived from SOFA, rather than SOFA
67** itself.
