Shirley background

https://doi.org/10.1351/goldbook.09355
In Auger electron spectroscopy and X-ray photoelectron spectroscopy, background calculated to fit the measured spectrum at points at greater and lesser kinetic energy than the peak or peaks of interest, such that the background contribution at a given kinetic energy is in a fixed proportion to the total peak area above that background for greater kinetic energies.
Note: Fitting to the background can be made by averaging over a given number of energy channels.
