EELS spectrum or spectrum image
Verify energy offset, dispersion, exposure, collection context and available zero-loss information before quantitative edge analysis.
EELS
Background, edge and integration windows stay explicit.
Work with spectra and spectrum images using visible energy calibration, background model, fit range and integration limits. Results are measurements, not hidden classifications.
Spectrum to edge-resolved evidence
Preprocessing, background fitting, edge measurement and interpretation remain separate and inspectable.
Background model and integration windows
Select the pre-edge interval, fit the power-law background, inspect fit residual and choose the post-edge integration window. Deconvolution or thickness correction is reported only when explicitly applied.
Edge intensity, maps and fit quality
SpectrumBackground-subtracted edge integral and calibrated energy onset
Spatial resultEdge-integrated map tied to the spectrum image
QualityFit residual, signal window, noise context and excluded channels
AdvancedWhite-line metrics or thickness-related outputs only where assumptions are satisfied
Spectra, maps and method record
The result package preserves both the measured spectrum and every model-dependent derived quantity.
