Function rvMasyrToKms( rvMasyr, plxMas )

Description:
Converts from normalised radial velocity in mas/year to unnormalised radial velocity in km/s.

The output is calculated as AU_YRKMS * rvMasyr / plxMas, where AU_YRKMS=4.740470446 is one Astronomical Unit in km.yr/sec.

Parameters:
rvMasyr (floating point)
normalised radial velocity, in mas/year
plxMas (floating point)
parallax in mas
Return Value (floating point):
radial velocity in km/s
Signature:
double rvMasyrToKms(double, double)
