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: 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?
