The electron bandstructure for chromium (bcc) was calculated using the program Quantum Espresso (version 5.3.0) in Winmostar (version 8.034). A bandstructure calculation always calculates a finite number of bands. Usually these are the bands around the Fermi energy. For energies further away from the Fermi energy, bands will be missing. To check that the bandstructure is correct in the range that is plotted, make two calculations including different numbers of bands and only plot the energies where both calculations overlap.
