INTENSITY

        SHOW INTENSITY [VarName]

    Compute  and  display  the intensity distribution of the specified SIC vari-
    able, in logarithmic scale, and fit a Gaussian to the histogram of pixel in-
    tensities per channel. VarName  must be the name of a 2-D or 3-D  SIC  image
    variable.

    If  no  VarName  is specified, the last displayed image (by SHOW or VIEW) is
    used. If none was ever displayed, SHOW selects among SKY,  CLEAN  and  DIRTY
    images  in this priority order.  Variable SCALE (if non zero) is used to de-
    fine the displayed intensity scale.

    See SHOW NOISE for a linear scale equivalent.
