[Wien] problem encountered while calculating DOS- attention: Antoine

There is no point in plotting such sharp states.
Simply check out their eigenvalue, eg. in case.scf1.
 
What more can be said about a delta function than its position?

Sure ! Moreover your bands at such low energies are almost atomic-like, i.e.
extremely narrow. Which means that if you want to plot DOS for semi-core
states, you need to choose a very small DE parameter (0.002 Ryd. may be
larger than the band width for semi-core states...), unless tetra will miss
the bands and give a zero DOS value in that energy range. Try DE = 0.0002,
Gauss-Broadening = 0.0003, and decrease further until you see something
coming out.

If you really want to plot semi-core states...
