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:
