[Wien] Correct way of band structure calculations for exact exchange

[Yurko Natanzon]

Dear wien2k users,
Could you guide me what is the correct way of calculating band
structure for exact exchange/hybrid functionals?
I've tried the following:
1. x lapw1 -band -up -orb
and
2. x lapw1 -band -up

Of course, the results were completely different. Also, if the second
variant is correct (it seems so) then when do I use the -orb switch
for calculation of band structure. Only for LDA+U?
