Thanks you! Yes, the numbering was confusing. I corrected it. That's the problem. They supposed to be the same. That's why I'm trying to evaluate the fitting, in order to find the best.. Is it correct? I don't know what else I can do... The first group has higher R^2 than the second. Is it a...

Thank you! :-) Here is the fitting:

Hello! :-) I' have a problem... I fitted experimental data with a second order exponential theoretical curve: y = A1*exp(-x/t1)+ A2*exp(-x/t2) + y0 and I have these data for 4 repetitions of the same experiment: first time: Reduced Chi-Sqr = 6,81066E-4 Adj. R-Square = 0,41005...
