[Wannier] Question on localization of WF

[elchatz at auth.gr]

Hello all,

I would like some clarification on the localization of WFs.

I have calculated bulk transport using Wannier90, however, the Im/Re  
ratio of the WFs is on the order of 1e-2 to 1e-3. How can I know if  
the conductance results are "accurate"?

Would it suffice for the WFs spread to be smaller than the volume of  
the unit cell?
