Data input
  • Load single or multiple records
  • Check and assign geometry
  • Optionally load velocity model for reprocessing
Data processing
  • AGC, trace balance, and time-variant scaling
  • Frequency filtering
  • Trigger delay correction
  • Undo or redo multiple steps in data processing
Event fitting
  • Define initial velocity model
  • Calculate T-X curves of reflected and refracted waves
  • Plot T-X curves on seismic records
  • Interactively adjust velocity model to fit T-X curves with reflection and refraction events
  • Output velocity model
