Convert rest frequency to velocity.

Parameters:

rest_freqQuantity: Observed frequency.
radial_velocityQuantity: Radial velocity of the source relative to the observer.
doppler_restQuantity: Rest frequency of the line.
doppler_convention{“radio”, “relativistic”}, default: “radio”: The Doppler convention to use.

Returns:

velQuantity: Velocity.
