Band ordering in GW eigenvalues

Concerns issues with computing quasiparticle corrections to the DFT eigenvalues - i.e., the self-energy within the GW approximation (-g n), or considering the Hartree-Fock exchange only (-x)

Dear Daniele,

thanks for this. I am glad to hear that I am not making a fundamental mistake in the GW calculation. I will go through the interpolation again and I
will redo the convergence tests for the given k-points and the bands explicitly. I will keep you posted!

Best,
Ivona
