[Wien] Units in case.qtldn file

[Lukasz Plucinski]

Hello,

I did spin-polarized Fe(100) slab calculation to get minority surface 
states. I wrote a script to read case.qtldn and case.outputirdn to plot 
only bands of the certain symmetry (because photoemission in my geometry 
can only see even states). To see surface states nicely I plot only 
these which have more than 0.2 total charge in case.qtldn file (atom and 
k-resolved). Of course this "0.2" is an arbitrary number, but for my 
particular case it produces nice and clear picture.

My question is trivial, and most likely it has been answered many times 
before:

What are the units of this "0.2" number ? What are the units in the 
case.qtldn file ?
