[Ifeffit] problem with E0 (enot) parameters

Hi Zajac,

What happens if you constrain all E0's to be the same? In the fit  
where they come out large, what are the uncertainties in the E0's?  
What are their correlations with other fitted parameters? There has  
been some debate in this list on the past as to how useful it is to  
allow for different E0's for different paths. It may be that Artemis  
is shifting the E0's for those paths in lieu of some other correlated
