Hey EPR Community

Having some trouble fitting the simulation to the actual data. Code as follows:

clc

Sys.Nucs = 'Eu';
Sys.g = [1.95 1.99];
A_Eu = [.01 .01 .011]; %cm^-2
Sys.A = [A_Eu]*30e3 % cm^-1 -->MHz
Sys.AFrame = [0 .1 0]*pi/2;
%Sys.lwpp = [0 0.65]
Exp.mwFreq = 9.6; %GHz
Exp.Range = [5 695];
Vary.lw = 1.5;
% Vary.g = [0 0.02];
% Vary.lw = 0.3;
Opt.Method = 'perturb';
Opt.nKnots = [11 0];
pepper(Sys,Exp,Opt);
esfit('pepper',spc,Sys,Vary,Exp);

Not sure how to proceed so any advice would be helpful. Thanks!
