Hi, the errors are standard deviations. For the standard fitting options, the fitting parameter uncertainty is defined [here](https://github.com/ECSHackWeek/impedance.py/blob/6b80b4129115e246adb90f2179d088f3ada5a5ff/impedance/models/circuits/fitting.py#L144). This line is calculating the square root of the diagonal of the...

Actually, it's already documented, see `impedance.models.circuits.fitting.circuit_fit` here: https://impedancepy.readthedocs.io/en/latest/fitting.html

Ah, I understand now -- yes, these parameters need to be taken with a grain of salt, as estimates of parameter confidence from nonlinear curve fitting is not fully settled....
