Is there a Mathematica function that can simply do this? Or if anyone can give an idea of how to do the multi-peak fitting using Mathematica.

The number of peaks is unknown and should be detected automatically, and the fitting model must also be built accordingly. The peak model is given and fixed (all peaks are fitted by the same model), but its particular form (which will be input) can be Gaussian or Lorentzian or some other customized functions. Following is an example of fitting the data using three peaks (such that the data ~ peak1 + peak2 + peak3). If there is a strong demand for kinetic energies, it could be implemented in future versions.I am wondering how to implement the multi-peak detecting and fitting in Mathematica.

Only a positive 'binding energy' scale works - however, this should be the most common case.

Data with 'kinetic energy' as x-axis (in waveform format or not) can not be analyzed with the Fit Assistant.

computes the overlap of two selected waves and saves it to a new wave returns the absolute path of a selected wave (so it can be easily found) You can sign off anytime you want using the same address.īesides the graphical interfaces, XPST comes with several commandline functions. If you want to stay informed about updates or other issues, just send a blank mail to: is not a support contact - it only serves to keep you informed about changes.

Copy/Move the folder 'XPSTHelp' to the folder 'Igor Help Files' in Igor's main folderīefore you upgrade to a newer version of XPST, please remove all files associated with your old version from Igor's folders.

Copy/Move the folder 'XPST' to the folder 'Igor Procedures' in Igor's main folder.

If you still run Igor 6, you have to download a previous release. The Igor 7/8 version is not compatible with Igor 6. XPST was initially developed with Igor 5, but a major revision was made with Igor 7. Several changes in the newest version of XPST were made according to this book about programming Igor. There is also a youtube channel with tutorials. As a special feature, a flexible multiplet function was implemented to facilitate a convenient analysis of complex spectra.

You can generate fit templates and you can export entire fit projects to share them with your co-workers. When a XPST fit project is started, a corresponding subfolder with all required data is generated and saved within the Igor experiment. It includes various graphical interfaces as well as commandline functions to facilitate the workup of XPS data. XPST is a program package for the analysis of X-ray Photoelectron Spectroscopy (XPS) data. Wide-Angle Neutron Spin Echo SpectroscopyĬurrent version: 1.3 (March 2018) for Igor 7/8.
