11 ** Given:
12 ** s1 double scalar to multiply position component by
13 ** s2 double scalar to multiply velocity component by
14 ** pv double[2][3] pv-vector

19 ** Note:
20 ** It is permissible for pv and spv to be the same array.

41 ** This library is derived, with permission, from the International
42 ** Astronomical Union's "Standards of Fundamental Astronomy" library,
43 ** available from http://www.iausofa.org.
44 **
45 ** The ERFA version is intended to retain identical functionality to
46 ** the SOFA library, but made distinct through different function and
47 ** file names, as set out in the SOFA license conditions. The SOFA
48 ** original has a role as a reference standard for the IAU and IERS,
49 ** and consequently redistribution is permitted only in its unaltered
50 ** state. The ERFA version is not subject to this restriction and
51 ** therefore can be included in distributions which do not support the
52 ** concept of "read only" software.
53 **
54 ** Although the intent is to replicate the SOFA API (other than
55 ** replacement of prefix names) and results (with the exception of
56 ** bugs; any that are discovered will be fixed), SOFA is not
57 ** responsible for any errors found in this version of the library.
58 **
59 ** If you wish to acknowledge the SOFA heritage, please acknowledge
60 ** that you are using a library derived from SOFA, rather than SOFA
61 ** itself.
