Listing and Plotting Velocity Information

The task uvlist can be used to list information about the frequency and velocity setup, with the options=spectral listing. This prints out the velocities for a visibility record. It is suggested that you do this before proceeding much further, to ensure that the velocity and rest frequency information is what you expect.

The task varplt can be used to plot or list the observatory's radial velocity as a function of time. Use the parameter setting yaxis=veldop.
