Hi,

I've been working a 3pESEEM fitting script for a while and I've noticed that when you output the data, there is a time-domain offset between the experimental set, and the simulated set. I assume this is due to deadtime in the experimental spectrum. Does esfit take deadtime into consideration when fitting ESEEM data? Or does this need to be manually input through some set of parameters?

Thanks!

esfit uses the simulation function provided as the input, combined with the fitting parameter input (p0 or {Sys0,Exp0}), to get the simulated data that is compared to the fitting target. It relies on the input provided by the user giving a simulated dataset that matches the target (same start and end values of the x-axis, same number of points).

In saffron the inter-pulse delays can be specified to match the experimental values as follows (see saffron user guide for more details):

% Three-pulse ESEEM
Exp.Sequence = '3pESEEM';
Exp.tau = 0.120;   % fixed tau value, in µs
Exp.T = 0.100;     % initial T value, in µs
