28             **
29             ** 1) The result is computed even if any of the range checks fail.
30             **
31             ** 2) Negative ihour, imin and/or sec produce a warning status, but
32             ** the absolute value is used in the conversion.
33             **
34             ** 3) If there are multiple errors, the status value reflects only the
35             ** first, the smallest taking precedence.

63             ** available from http://www.iausofa.org.
64             **
65             ** The ERFA version is intended to retain identical functionality to
66             ** the SOFA library, but made distinct through different function and
67             ** file names, as set out in the SOFA license conditions. The SOFA
68             ** original has a role as a reference standard for the IAU and IERS,
69             ** and consequently redistribution is permitted only in its unaltered
70             ** state. The ERFA version is not subject to this restriction and
71             ** therefore can be included in distributions which do not support the
72             ** concept of "read only" software.
73             **
74             ** Although the intent is to replicate the SOFA API (other than
75             ** replacement of prefix names) and results (with the exception of
76             ** bugs; any that are discovered will be fixed), SOFA is not
77             ** responsible for any errors found in this version of the library.
78             **
79             ** If you wish to acknowledge the SOFA heritage, please acknowledge
80             ** that you are using a library derived from SOFA, rather than SOFA
81             ** itself.
