This is a great tool! I'm using it to fit a quadratic function to a magnetic field over a 3D lattice.
I'm interested in the uncertainty in the fit parameters. Is it correct to interpret "ParameterStd" as this uncertainty? (If not, what is?) And it is a little puzzling to me as to how "ParameterStd" is determined given that I have not provided the measurement uncertainty to the code. Can you explain a little bit about how this "ParameterStd" is computed?
