Hi all, we performed a fit with the new ntuples and the following flags: -d -b -rew 10 -wF sysWd/dom_0.inc -debug Below is what we find. Is this consistent with what you are getting? Can we start making fits to evaluate the systematics for the unfolded spectrum or do you expect changes to the fitting code or strategy? We noticed that the chi2 went down to about 0.41..
