Design principles of the wxEWA spectrum evaluation program for the photoelectron spectroscopy

The main design principles of a multispectrum, multimethod spectrum evaluation application are described. The data handling allows to build refined and complex data evaluation models and thus to investigate complex problems using fine and established methods quickly, without the need of writing highly specialized spectrum data evaluation programs for the individual data evaluation tasks. The program is flexible and user friendly, equipped with XPS specific evaluation facilities. Only procedures published in refereed journals are implemented, typically several methods for solving the same task, thus allowing to compare different data evaluation methods on the same experimental data. The provided data evaluation methods involve simultaneous evaluation of experimental data taken at different experimental parameters or spectral data resulting from different experimental investigations, too. The used multi-platform base package allows to build and run the application on practically all popular platforms today. The application is available for free from its Web site.
