Project Description

Several tools support phase-velocity and dispersion analysis:

  • greda: Calculates Fourier-Bessel coefficients or a slant stack for waveform data.
  • phadi: Calculates a single-mode dispersion analysis for waveform data.
  • gabor: Calculates a spectrogram (gabor matrix) for waveform data.
  • grereso: Calculates a resolution analysis for wavefield transforms.
  • grepg: Plots results from the analysis programs.
