However, some of my data are not fitting properly. I was able to fit all the curves, with acceptable errors, fixing the X0 value in the parameters section. But, I don't know how these values (X0, A1, A2) presented in the parameters before the fitting were calculated by Origin. Can anyone help me with that? Your message is highly appreciated.
