They are compared with LDA and LDA U band structure calculations. For Sr2RuO4 and BaCo1-xNixS2 energy excitation dependence of O K alpha and S L-2,L-3 XES near the O Is and S 2p threshold is found which is attributed to excitation of inequivalent oxygen and sulphur atoms in plane and apical sites, and corresponding O 2p and S 3s3d DOS are mapped.
