[DISPLAY\]LOAD File /RANGE Min Max Type
Load only the channels between the First and Last defined by Min Max and
Type. Type can be CHANNEL, VELOCITY or FREQUENCY. If the Data cube has
no Frequency/Velocity axis, only CHANNEL is allowed.
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.
The /RANGE option is not (yet) allowed for FITS files.
