The "Calculate" button is used here because Newton's method, an
iterative approach, is used to solve for N and so each calculation can
take a significant amount of time and in some cases no solution may be
found.

The equation for JCM breakdown is not given here due to space
constraints, but can be found elsewhere at this
site.
