Comparison of Background Types
Comparison of Background Types
Linear Background versus Shirley Background (no iteration) versus Iterated Shirley Background versus
Sherwood Background versus Tougaard Background versus Vegh-Castle-Salvi Background
2 parameter Tougaard versus Iterated Shirley – Raw Spectra of natural crystal of Fe2O3 (Hematite)
Fe (3p) – Fe (3s) spectrum
Raw Ti (2p) Spectrum without a Background – Vertically Zoomed – Peaks above BE=467 eV are probably Intrinsic satellites
Shirley Background:Â Not Iterated versus Two (2) Iterations
Linear Background – Includes two (2) satellites above BE=467 eV that are either shake-up or multiplet-splitting structures
Linear Background – Vertically Zoomed – includes satellite structures
Single (1) Iteration of Shirley Background – includes satellites
Linear Background versus Iterated Shirley Background – Same Endpoints – Which background is more useful or correct?
Linear Background versus Iterated Shirley Background – VERTICALLY ZOOMED to reveal usefulness of endpoints selected
Iterated Shirley Background – Limited to Two (2) Main Peaks – Ignoring satellite structures at higher BE – Useful ?
Linear Background – Limited to Two (2) Main Peaks – Ignoring satellite structures at higher BE – Useful?
