H/V and Spectrum results are the same, except for:

  • the labeling of the Y-axis
  • the default number of individual curves (1 in the H/V case; 3 in the spectrum case)

The examples shown here below in this are based on H/V results

For the Spectrum results, simply replace H/V by Spectrum when reading the notice.


The results are obtained after adjusting the windowing and processing parameters in the H/V or Spectrum 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.


Curve graph

H/V curve

The curve graph shows:

  • individual curves from the selected windows, with the color of the corresponding window in the signal sheet (provided All window of the H/V options or Spectrum options in Preferences has been selected
  • the average curve (black line)
  • the amplitude standard deviation curves (dashed lines)
  • the peak frequency standard deviation domains (the two vertical gray areas)


The peak frequency is the value at the limit between the two gray areas.

Note: the limit between the two gray areas and the top of the average curve peak are obtained in two different ways:

- the average curve is obtained by averaging all the curves from the individual windows

- the average peak frequency is obtained by averaging the peak frequency of all the curves from the individual windows.

It may thus occur that they do not coincide.


The name of the receiver appears above the top right corner of the curve plot.

Note: the name of the station and the graph are not grouped. Both of them must be selected so as to move the two of them together.


H/V average curve without individual curves

If the item All windows of the H/V options or Spectrum options in Preferences has not been selected the color curves do not appear

Curve parameters

H/V parameters

The curve parameters are displayed in a small pale yellow pop-up window when moving the cursor into the graph or into the graph title in which are indicated:

  • the receiver name.
  • the peak frequency value with its standard deviation. This value is the limit between the two gray areas, not the value of the average curve peak.
  • the peak amplitude with its standard deviation. In case of several peaks, all frequencies and amplitudes are shown.
  • the category of the curve, which has been defined by the operator (see next section). This parameter is more useful when several H/V curves are processed.


Cursor position (X,Y)

A bright yellow pop-up window also appears to give the coordinates of the place where the cursor points to.


Parameter box and cursor position (X,Y)

Both windows may appear together on the graph.


Graph parameters may be customized, and its appearance modified by using a Make-up.

Graph menu

Graph tools

With a right-click outside the graph a pop-up menu appears (this menu is also present at the top of the window when running geopsy under Windows or Linux).

Only Tools is a geopsy specific feature. The other items are described in the Graphic Sheet menu reference manual.



Processing several stations

When processing several (at least two) stations, results appear in two Graphic Sheets:

  • a window with all individual curves
  • a window with a summary

It is possible reprocess some or all receivers.


Individual curves

For a description of the individual curves see Curve graph


Individual H/V curves


The curve graph(s) appearance may be customized.

H/V summary

The summary window includes

  • two graphs summarizing the curves
  • a frequency-distance graph with color-coded amplitude along a profile
  • a map showing the distribution of the stations in a geographical system

Note: the two maps appear only when the coordinates of the sites have been entered in the data base


Summary curves

Two graphs summarizing the individual curves appear at the top of the window:

  • individual curves all together
  • a single curve showing the average of all individual curves, with amplitude and frequency standard deviations
H/V summary curves of the above eight single curves


Map

When the receiver coordinates are included in the data base, a geographical map is displayed.

Each location is characterized by three items:

  • a symbol at the location of the point
  • a color bubble, scaled to the parameter (frequency or amplitude) shown on the map
  • a label, which is either the parameter (frequency or amplitude) value, the station name, or which can be omitted

In the default map the receivers are displayed with a frequency color bubble and the receiver name.

Geographical distribution of the receivers with color coded frequency symbols and receiver names


Sub-item Map options

The display parameters may be changed with the pop-up Map options sub-item in the Tools item of the the pop-up menu obtained with a right click outside the map.


Reprocessing some or all stations

Selected H/V curves to be reprocessed (Stations 003 and 010)


Select the curves to be re-processed and change the parameters in the H/V or Spectrum Toolbox


Selecting no curve or all curves have the same effcet: all curves will be re-processed.


Partial re-processing dialog box

No dialog box appears when all stations are re-processed.

When only some of the stations are selected, a dialog box appears with the following options:

- Selection: re-process only the stations listed in the dialog box

- All: re-process all stations of the current processing
