I'm trying to fit an Exp Decay 1 function to an eye movement response. The peak value is approx 5 degrees and then decays towards 0. I have used the data selector to choose an appropriate range (from the top of the response and some secs after the recording flattens out. My A1 value gets extremely high (millions), I have tried to fix (lock) the A1 to 5-10 but this gives an incorrect fitting of the curve. Does anyone know what I'm doing wrong?
