initial and boundary conditions and one must
feel out a large part of parameter space before
one understands the system. The same is true
for one or two tomographic images. Although
a picture may be worth a thousand words a
single color tomographic cross-section can be
worse than none. Although quantitative and
statistical interpretations of tomographic models
are required to fully capitalize on their informa-
tion content, much can be learned by looking
at hundreds of tomographic maps and cross-
sections from different groups. Numerous color
images of various tomographic studies can be
