convert a doppler type value to a real radial velocity

Synopsis
toradialvelocity(rf, v0)

Arguments

rf	in	radial velocity reference type
		Allowed:	string
v0	in	doppler value
		Allowed:	doppler measure

Returns
radialvelocity measure

Description
toradialvelocity will convert a Doppler type value (e.g. in radio mode) to a real radialvelocity. The type of velocity (e.g. LSRK) should be specified

Example

- print a := dm.doppler('radio',0.4)
[type=doppler, refer=radio, m0=[unit=m/s, value=1.19917e+08]]
- dm.toradialvelocity('topo',a)
[type=radialvelocity, refer=TOPO, m0=[unit=m/s, value=1.41079e+08]]
