      /VELOCITY V1 [... [Vn]] [/WIDTH Width [TYPE]]

    Specify around which velocities the line emission should be found.   Veloci-
    ties  V1  to  Vn  must be in km/s. The full width of the 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
