Did you ever plot a DOS for the regular structure and the core-hole supercell ?? I assume, the material is an insulator, so EF should be at the top of the valence band, just below the gap. In the core-hole calculation you get of course a metal, and EF is NOT at the top of the valence band, but

Dear Peter and all list members, [Peter, thanks again for the response below.] I am modeling XPS binding energy using a one-half core-hole, offset by background charge. I am looking at the Al-2p states in the Al-P-O-H system, and looking at shifts in the XPS energy between hydrated and
