9. Fitting Frame
This frame calculates a polynomial fit to the eigenvalues. It uses the form
E(v) = Te + w(v+1/2) - x(v+1/2)2 + y(v+1/2)3 + z(v+1/2)4
The number of eigenvalues to use in the fit can be set as well as whether or not to use the x, y, or z terms. The results of the fit are displayed and the calculated fit is shown in the eigenvalues frame.
