The SIV toolbox provides a number of utilities to evalaute mistfits/similarity of the waveforms, and to compare source models:
- Waveform plots
- Assesment of Waveform misfits/similarity using different metrics: correlation analysis, root-mean-square error, 1-norm, 2-norm, and percentage variance reduction
- Analysis using Fourier Amplitude Spectra
- Waveforms comparision using the time freqency envelope and time phase envelope as parameters for misfit/goodness of fit between two signals
- Summary statistics for source models
- Contours and grid comparisions of source models
The SIV project, and in particular, the benchmark exercises, has been discussed in the following publication:
