<br>
I see a lot of papers that give the weight of the Wannier function as <br>
a function of distance from the center, and I was wondering if there <br>
is an easy way to extract this in order to assess localization <br>
properties. For example, would a gaussian fit from the WF center to a <br>
radius equal to the spread be a appropriate?<br>
<br>
Note that I will also accept any tutorials on this if there exist.<br>
