1 MVIEW Interactive viewer of spectra cubes
        MVIEW

    is  an  X‐Window viewer for GILDAS data cubes. MVIEW is oriented towards
    fast interactive display of 3‐D data cubes, and has  capabilities  which
    allow it to prepare parameter files for some GILDAS task.

    * To increase the speed of interactive cursor, desactivate the zoom win‐
    dow, by clicking the right button in it and select zoom off.

    * In NORMAL mode, press button1 to visualize X,  Y,  Z  coordinates  and
    spectrum  along  Z.  A Button1Press immediately followed by a Button1Re‐
    lease in the integrated mean window memories a summit of a polygon in  a
    queue;  same  action with button2 removes the last polygon summit in the
    queue; click button3 to close the polygon and visualize  the  integrated
    spectrum inside the polygon on the right side.

    * In SLICE mode, press button1 and drag the mouse to define the slice.

    * In 3D AREA mode press button2 and drag the mouse to define a reference
    subset in the mosaic; when the cursor falls into an  other  subset,  the
    box is propagates itself from current to reference subset or from refer‐
    ence to current subset; release button2 and press anywhere else  to  se‐
    lect  another reference subset; Press button1 (resp button3) anywhere to
    define first (resp last) subset. In the spectrum window, the  first  and
    last  subset  are  given by the position of the big tics under the inte‐
    grated spectrum; drag the tics with button1 to  compute  the  integrated
    mean between the tics.
