RESEARCH
Currently working on KherveFitting, a tool for fitting XPS data.
KherveFitting is a fully Open Source XPS Fitting software that is simple , snappy, easy to use and available across severall platforms (Windows, Linux). Currently , only the binary version of Windows is available but the source python files are available for Linux and MacOS. The software is written in Python using well known libraries: Numpy, lmfit, matplotlib, panda.
KherveFitting can open Excel files (.xlsx) or import/convert VAMAS files (.vms) into Excel format. 5 background types available: Tougaard, Linear, Shirley, Smart, Adaptive Smart. Various peak fitting models: Product and Sum of Gaussian and Lorentzian (GL & SGL), Voigt, Asymmetric Lorentzian (LA) and many more . Fit single peaks or doublets. Doublet splitting and RSF values are stored in a library file. Several intensity calibration available:TPP-2M, Scoffield, Wagner. Atomic concentration acurately calculated and matching with Thermo Avantage software.
Features
Convert Vamas (.VMS), Kratos (.kal), Phi (.spe), Thermo (.xlsx, .avg) into Excel files
Background: Shirley, Smart, Adaptive Smart, U4-Tougaard
Change background offset with SHIFT+mouse
Peak shape: GL, SGL, LA, Voigt, Pseudo-Voigt, ExpGauss
D-parameter Measurement
Open / Save Peak Library
Intensity calibration: TPP-2M, Wagner, Scofield, EAL
Transmission function correction
Multiple RSF libraries available matching CasaXPS and Thermo Avantage
Angular Correction Factor
Automatic binding energy correction
High number of Constraints.
Add doublet available with doublet splitting library available in a txt file
Undo / Redo capabilities
Peaks can be locked to each other
Most part of the fit can be done by key shortcut rather than the mouse
Copy, rename, delete, crop, or join Core Levels
Smooth, derivate, integrate Core Levels
Survey Identifications and label
