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

LEME vparLEvparMEf

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)MC

Fit

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 +:
