Dear WIEN users,
When I calculate the zinc-blende InAs I find a strange problem.
The As 3d is a local orbital and its original energy parameter is -2.67Ry.
But from the self-consistant results we find the eigenvalue for As 3d is
-0.125Ry. This result is completely unphysical. Why not the program give a ghost
band error message? This is the case.in2c file.
