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).
