Shirley Background Correction
What it does
Shirley background correction is commonly used for XPS spectra to estimate background signals caused by inelastic scattering.
When to use
Use it for XPS spectra where the background gradually changes under the peak region.
How to use in SmartPlot
Analyze -> Baseline Correction -> Shirley
Parameters
- ROI: selected x-range
- Endpoint mode: auto / manual
- Negative clipping: on / off
Example workflow
- Import XPS data.
- Select the peak region.
- Apply Shirley baseline correction.
- Check corrected spectrum.
- Continue with peak fitting if needed.
If ROI is too wide or includes unrelated peaks, the baseline may become unstable.
