[Wien] incorrect DOS

Thanks for your reply, Hong.

I checked the partial DOS and you are right; this band at -10 eV is from Hf
f states.

But I need some help to understand this:
If I understand it correctly, there can be only one correct DOS. 
So which one would it be: - the one from pseudopotential calculations or the
one calculated using Wien2k?

Or in other words, should there be a band from the f states at -10 eV in
this case or not?


Regards,
Manish
