         Paul: First of all, BB, thanks for your reply. Could you 
explain what you mean by "shallow"? To extend the angle analogy, are 
they acute or obtuse and, what effect do \left and \right achieve in 
this context? I was under the impression that they matched the height 
of the brackets with that of of the tallest object within.

Thanks
Paul
