MAVGDSP   Disposition of meridional averages, if computed <MERAVG> (one CHAR-
           ACTER value, default is MAVGDSP = 'PLTDISC').

           'PLTDISC' Plot the averages, then discard.  The unaveraged data are
                     the basis for all subsequent processing. (Default)
           'PLTPROC' Plot the averages, then proceed with processing using the
                     averages as the basis for all subsequent operations.  The
                     unaveraged data are discarded.
           'PROC'    Proceed with processing using the averages as the basis
                     for all subsequent operations.  The unaveraged data are
                     discarded.  (Same as 'PLTPROC', except that the averages
                     are not plotted.)

           This ICP is ignored unless MERAVG = 'YES' is also specified.
