            [GREG2\]MEAN [/CLIP Nsigma]

        computes crude statistics on the part of the Regular  Grid  array  lying
        inside  the  current polygon. Blanking values as defined in SET BLANKING
        are ignored. The results are displayed (some of them  according  to  the
        current ANGLE_UNIT), and stored in the variables:
        - POLY%NPIX (number of non-blanked pixels in the polygon),
        - POLY%MIN
        - POLY%MAX
        - POLY%AREA (area of the non-blanked pixels),
        - POLY%SUM (integrated intensity),
        - POLY%RMS.

        If  option  /CLIP is present, iterative kappa sigma rejection is used to
        reject outlier pixels.
