    With regard to Sylvia's note below: if you downloaded version
    4.2.0.a025 of NCL (which was released September 16), and you want to
    get the new version of gsn_code.ncl that Sylvia mentions, then you
    can get it from:

      http://ngwww.ucar.edu/ngdoc/ng/ug/ncl/gsun/scripts/gsn_code.ncl

    You only need to download this script if you were panelling plots in
    the past that were slightly different sizes, and are suddenly seeing
    some extra white space around your paneled plots.

    Put this script in the directories:

       $NCARG_ROOT/lib/ncarg/nclscripts/csm
       $NCARG_ROOT/lib/ncarg/nclex/gsun

    and you should be set.

    Cheers,

    --Mary
