It seems the parameters fromt he fit are wrong. This is my data
and here are the results of the fit
f =
General model:
f(x) = a*exp(-((x-b)/c).^2)+d
Coefficients (with 95% confidence bounds):
a = 0.4218
b = 0.9157
c = 0.7922
d = 3351 (-646.9, 7349)
"b" should be close the 7 so I can't figure out whats going wrong with the fit, and then to plot the fit as well.
It fits fine in Mathcad.
