For each multiplet of this branch, the upper plots show the
correlation confidence level, in percent, for the lateral correlation
of the estimated splitting function and the predictions of Harvard
model S12_WM13 and Scripps model SH.10c.17.  A seperate line is shown
for correlations at each (even) structural degree.  Confidence levels
for lateral correlations are discussed in the paper "Correlations
Between Global Features of Terrestrial Fields" [Mathematical Geology,
16, 155-171, 1984], by D.H. Eckhardt.

     The lower two plots compare the root-mean-squared amplitudes
of the estimated splitting functions and model predictions at each
structural degree.   This is done using the function:
log(R); R=(estimated amplitude)/(predicted amplitude).
