COMPOSITE

        SHOW COMPOSITE [WIDTH|PEAK]

    Display the 3 "moments" images derived from a datacube by  command  MOMENTS,
    and  the integrated line flux computed by command FLUX.  The contour spacing
    for each image is controlled by its own variable:
    AREA_SPACING   for the integrated area  M_AREA
    PEAK_SPACING   for the peak brightness MPEAK (in K)
    VELO_SPACING   for the Velocity field M_VELO (in km/s)
    WIDTH_SPACING  for the Width field M_WIDTH (in km/s)

    As for other image displays, CENTER and SIZE control the center and size  of
    the  image  (in arcsec). Limits for the Flux spectrum are computed automati-
    cally.

    The 3 selected moments are AREA, VELO and either PEAK or WIDTH according  to
    the 2nd argument (sticky value).
