1st try: fit the ME-LE data with the following function:

MEv
LEv
Simple chi-squared used for the fit:

where:
1st check: Fit for (ME-LE)MC after correcting for ME,LE differences with the MC:
ME-LE, no + (MC)
parMEv ME parLEv LE
(ME-LE)MCFit
parME and parLE indeed converge at 1.0
2nd check: Fit for (ME-LE)MC assuming no ME,LE differences besides +:
parLE = 0.728±0.591parME= 1.303±0.297
Fit values:

Now fit for (ME-LE)DATA assuming no ME,LE differences besides +:

Fit (ME-LE)MC again with less bins:
