MLWFs in magnetic systems without SOC
In this case one set of MLWFs is constructed for spin-up (seedname WF1) and a second one for spin-down (seedname WF2). The number of bands used for generating the MLWFs may be different between spin-up and spin-down. Using
<wannier>
<bandSelection minSpinUp="9" maxSpinUp="44"/>
...
</wannier>
means that for WF1 the spin-up bands from 9 through 44 are used and for WF2 the spin-down bands from 9 through 44 are used. However, if for example
<wannier>
<bandSelection minSpinUp="83" maxSpinUp="90" minSpinDown="70" maxSpinDown="82"/>
...
</wannier>
is used the set WF1 is generated from the spin-up bands from 83 through 90, while the set WF2 is generated from the spin-down bands from 70 through 82.
