from what I read, this is more like a numerical issue,
> expr sqrt($instant_error_gauss)
The statistical error (the variance) is computed based on the FEP
estimator, as well as on a Gaussian estimator (we assume th_at Δ/U/
I can only suspect here that your P_0 is heavily skewed, or that you
are very far from a converged estimate of your free energy.
