Welcome to lmfitxps, a small Python package designed as an extension for the popular lmfit package, specifically tailored for X-ray Photoelectron Spectroscopy (XPS) data analysis.
While lmfit provides simple tools to build complex fitting models for non-linear least-squares problems and applies these models to real data, as well as introduces several built-in models, lmfitxps acts as an extension to lmfit designed for XPS data analysis. lmfitxps provides a comprehensive set of functions and models that facilitate the fitting of XPS spectra. In particular, lmfitxps provides several models that use the convolution of a Gaussian with model functions of the limit-package.
In addition to models for fitting signals in XPS data, lmfitxps introduces several background models that can be included in the fit model for fitting the data rather than subtracting a precalculated background. This is the so-called active approach, as suggested by A. Herrera-Gomez, and generally leads to better fit results.
For further details, please refer to the documentation of lmfitxps and lmfit!
To install lmfitxps, simply use pip:
