[Wien] LDA+U for La2O3

Still on the LDA+U for La. It should be true that the
LDA+U plays less role for the nearly empty 5d band.
However, why does LDA+U shift up the completely empty
4f band as shown in Czyzyk's PRB 49 14211(94) paper.
The authors used U=11.0 eV for the La 4f band in that
paper.

Thanks for help.
