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
15**
16** Returned:
17** spv double[2][3] pv-vector: p scaled by s1, v scaled by s2

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

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.
