WebbTo parametrize that, we calculate the potential energy surface (PES) of the local soft mode via density functional theory (DFT) calculations. From that, we extract the averaged displacement by considering the local minima in the PES. Furthermore, the oxygens are moved in those calculations according to the soft mode eigenvector.
