The radial velocity of JWST with respect to the Barycenter, in units of m/sec. Computed as the dot product of the total velocity of JWST relative to the barycenter in the direction of RA_REF/DEC_REF. The total JWST velocity is the sum of the JWST velocity relative to Earth and the velocity of Earth relative to the barycenter.
