Hello, I want to ask about parameters in ExpDec1.
I have experimental data about decay from 3 different conditions. I analyzed it by creating exponential decay fit curve. In the expdec1, the equation is y=y0 + a.exp^(-x/t). From the data obtained, the values of y0 (offset) and A (amplitude) are different in each of these conditions. I'm still confused about the value of y0 and amplitude. can you explain it to me? How does this value affect the decay?
Thank you

y0 represents the asymptotic value to which the measurement decays, while a + y0 denotes the measurement at t = 0. According to the fitting results, both y0 and A hold significance across all three fittings and should not be disregarded.
