 The radial velocity is usually given with respect to the barycenter, the center of mass of the solar system, to correct out the effect of the Earth's proper motion. The necessary correction can be calculated with the help of the script ''2_barycentric_velocity_correction.py''. The coordinates of the object, the observation time, the time zone, and the coordinates of the observatory must be specified: The radial velocity is usually given with respect to the barycenter, the center of mass of the solar system, to correct out the effect of the Earth's proper motion.
