20             ** 1) "Update" means "refer the position component of the vector
21             ** to a new date dt time units from the existing date".
22             **
23             ** 2) The time units of dt must match those of the velocity.

25             ** 3) It is permissible for pv and upv to be the same array.

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.
