A plugin for multi-event shear wave splitting analyses in SplitLab
StackSplit is a plugin for the MATLAB toolbox SplitLab (Wüstefeld et al., 2008) which allows applying multi-event techniques for shear wave splitting measurements (SWS) directly within the main program.
For details regarding installation and usage, see the UserGuide.
If you make use of StackSplit in your work, please acknowledge my paper in which the program is described:

Optionally, you can also cite the Zenodo DOI given above, which refers to the latest version of this GitHub repository.
Which stacking methods are available?
StackSplit grants easy access to four stacking schemes with which single SWS measurements made with SplitLab can be processed:
WS: stacking of error surfaces, normalized on the minimum/maximum (depending on input) of each single surface (Wolfe & Silver, 1998)
RH: modified WS method with weight depending on the SNR of each measurement and normalization regarding the available backazimuth directions (Restivo & Helffrich, 1999)
no weight: stacking of error surfaces without weighting following the PhD thesis of Wüstefeld (2007)
SIMW: simultaneous inversion of multiple waveforms in the time domain (Roy et al., 2017)
