The app calculates S and W parameters from the Doppler-broadened 511 peak of ionizing radiation.
SWCalculator might be quite useful for those physicists who work with positron spectroscopy. Main app features are:
- Supports a variety of different formats of input data files.
- Fit the 511 peak with four gaussian functions and subtract atan() background.
- Calculate S and W parameters for a series of spectra.
- Export data points, fit and chi^2 to a .CSV file.
- Save raster fit images.
The app is cross-platform, developed using CERN ROOT framework. GUI is based on the Xclass'95 widget library. You can download this software from the GitHub repository - download button above. As well as the source code - you can find precompiled binaries for MacOS, Ubuntu and Windows.
