ZFitter chi2 rooFit function not working for MC in 75X

[ldcorpe]

Hi,

There is some strange behaviour coming out of the chiSquared when applied to MC in the Fitter, here
https://github.com/ECALELFS/ECALELF/blob/master/ZFitter/src/ZFit_class.cc#L619

This produces a series of errors of the form:
[0] ERROR:InputArguments -- RooCurve::average(bw_res_Norm[invMass_SC]) invalid range (113.875,113.875)

I have checked already the name of the histogram and pdf, and this is consistent.
(MC_plot[invMass_SC] =(RooHist::h_s,RooCurve::bw_res_Norm[invMass_SC],TPaveText::bw_res_paramBox))

Anyway, the chi2 is not used directly for anything terribly urgent, and we can always implement by hand, so temporarily I am just commenting out the line so that we avoid being polluted by errors.

The Fitter seems to run fine otherwise,
