Color Plate A.4 shows a color map of the mean curvature
.
Because of anti-symmetry with respect to
, mean curvature has
contour line at
. Mean curvature varies from
to
. Both global maximum and
minimum curvature are located inside the domain at
and
respectively. There are seven local maxima and seven local
minima along the boundary. The local maxima are located at

. The local minima are located at

with

. Since the local maximum and minimum inside the
domain are on the same iso-parametric line
, we subdivide
into two sub-domains at this line.
