            MAP\XY_MAP [Filename] /TYPE LMV|VLM

        By  default,  XY_MAP  produces an LMV (position-position-velocity) cube.
        This can be overridden by the option /TYPE to reorder the dimensions  as
        VLM (velocity-position-position).

        VLM  is  the  natural  ordering  of the XY_MAP internal buffers, i.e. it
        should be faster to create the cube in this order. VLM  cubes  are  also
        useful  when  data  has to be accessed by spectrum (e.g. to use the cube
        with FILE IN mycube.vlm), as opposed to the LMV cubes  which  are  effi-
        cient for access by channel (image plane).
