[Wien] 3p or 4p PDOS for 3d transition metal

[tran at theochem.tuwien.ac.at]

Hi,

In WIEN2k, the plotting of the DOS is only for the valence states
(the core states are not shown). If they were plotted, each core
state would just correspond to a vertical line.

In the case where two sets of states with same angular momentum,
but different quantum number were both treated as valence,
then  case.outputst would tell you approximately were they should
appear on the DOS.
