the fits are collected in Table III. The coefficient of the term quadratic in the field strength is not physically the electric polarizability because it includes Born-level contributions from the magnetic moment. For this reason, we call this coefficient the pseudo-polarizability. In our choice of lattice units, the pseudo-polarizability is given by

with ξ as the anisotropy factor. The systematic due to the fit window is estimated by performing uncorrelated fits on the adjacent fit windows obtained by varying the start and end times by one unit. 

The extracted value for the pseudo-polarizability is roughly half the size of the electric
