Windowing and processing have been performed after adjusting parameters in the H/V Toolbox.


Signal and selected windows

Signal and selected windows before processing

After applying the windowing selection criteria, the selected windows appear in green on the signal sheet.

Signal and selected windows before processing

After processing, each selected windows appear with its own color on the signal sheet.


H/V graph

Signal and selected windows before processing

The H/V graph shows:

  • individual H/V curves from the selected windows, with the color corresponding to the clour of the window in the signal sheet
  • the average H/V curve (black line)
  • the amplitude standard deviation curves (dashed lines)
  • the H/V peak frequency standard deviation domains (the two vertical gray areas)

The frequency of the H/V peak is at the limit between the two gray areas.

The name of the reciever appear above the top right corner of the H/V graph.



Processing several receivers

Individual H/V curves
