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

H/V curve

The H/V graph shows:

• individual H/V curves from the selected windows, with the color of the corresponding window in the signal sheet (provided All window of the H/V options in preferences has been selected
• 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 receiver appear above the top right corner of the H/V graph.

Average H/V curve

If All window of the H/V options in preferences has not been selected the color curves do not appear
