COMPARE CUBE

        [DISPLAY\]COMPARE LeftCube RightCube

    Create  a  "view-like"  (see  HELP VIEW) display to compare side-by-side two
    data cubes. LeftCube should be 3-D SIC image variable, as RightCube.

    The display is divided in 3 columns:
    - The left column contains the integrated intensity image (bottom) and  cur-
    rent channel (top) for the LeftCube
    - The right column contains the same information for the RightCube

    The middle column has 4 panels, from top to bottom
    - Spectrum of current pixel of RightCube
    - Spectrum of current pixel of LeftCube
    - Integrated spectrum of RightCube
    - Integrate spectrum of LeftCube

    The  yellow  area  on  the  integrated spectra indicates over which velocity
    range the integrated maps are computed.  The integrated spectra are computed
    over the region displayed in the integrated intensity maps (default is whole
    displayed area).

    The green lines on the current spectra indicate the current displayed  chan-
    nel.   They  may correspond to the same velocity (R or RightClick / spacebar
    with cursor in the spectra) or different ones (I -- for Independent --  with
    cursor in the spectra).
