UV_FILTER /RANGE

            [CLEAN\]UV_FILTER [/RESET] [/ZERO] /RANGE Min Max [TYPE]

        Indicate that channels between the First and Last defined by Min Max and
        Type  contain  line  emission  and  should be filtered out.  Type can be
        CHANNEL, VELOCITY or FREQUENCY.

        For type CHANNEL, Min and Max indicate offsets from Channel 1 and  Chan-
        nel Nchan (the number of channels in the data set). Thus Max can be neg-
        ative: it then indicates Last = Nchan-Max. Also Min=0 and Max=0  implies
        loading all the channels.
