UV_SPLIT /RANGE

        [CLEAN\]UV_SPLIT [Degree [Compress]] /FILE FileIn [FileLine [FileCont]]
        /RANGE Min Max [TYPE]

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

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