Fit Zeta Factors to Standard
Follow this guide to update Zeta factors for all elements by performing a polynomial fit based on
Zeta factors of elements set using standard sample(s).
Step
Example/hints
1
Set up Zeta factors for the standard
sample.
Follow section 5.11.3 “Experimental Zeta
factors”
and see Fig. 5.11-4.

sample in red
(default initial values are
