            [CLEAN\]UV_FILTER [/RESET] /VELOCITY V1  [...  [Vn]]  [/WIDTH  Width
        [TYPE]]

        Specify  around  which  velocities the line emission should be filtered.
        Velocities V1 to Vn must be in km/s. The full  width  of  the  filtering
        window around every frequency can be set by option /WIDTH.  The optional
        argument TYPE indicates the type of width: FREQUENCY (in MHz),  VELOCITY
        (in  km/s)  or  CHANNEL (no unit), the default being FREQUENCY.  The de-
        fault width is the current channel width.
