The Integration Results dialog box displays the integration results for a region on an Sv echogram.
To display the Integration Results dialog box for a region:
Click a region on an Sv echogram.
On the Shortcut menu (right-click), click Integrate Region.
The following information and settings are available:
Note: The analysis variables that are displayed differ depending on whether you are working in depth mode or range mode, see About depth and range mode.
|
Analysis variable |
Description |
| General | |
|
Sv mean |
The mean volume backscattering strength. |
|
Sv minimum |
The minimum Sv value (that is above the below threshold value of -999 dB) included in the integration. |
|
Sv maximum |
The maximum Sv value included in the integration. |
|
NASC |
The Nautical area scattering coefficient (sA as used by Simrad). |
|
ABC |
|
| Domain | |
|
Height mean (in depth mode) |
The average thickness/height of the region calculated over the pings included in the integration. See: Thickness_mean and Height_mean for more information. |
|
Depth mean |
The average range/depth of samples included in the region. See About depth and range mode. |
|
Beam volume sum |
The sum of the beam volumes of all pings in the region. See Beam_volume_sum for more information. |
|
Exclude below line depth mean |
The average range/depth of the line entered in the exclude below text box (on the Analysis page of the Variable Properties dialog box) over pings with a "good" line status included in the integration. Generally the exclude below line would be the bottom. See About depth and range mode. |
| Counts | |
|
Good samples |
The number of sample data points actually included in the integration. Data points can be excluded if they fall within bad data regions, above an "exclude above" line or below an "exclude below" line. May be exported as Good_samples. |
| Bad samples |
The number of bad data samples in bad data regions. May be exported as Bad_data_samples. |
| No_data samples |
The number of no data samples. May be exported as No_data_samples. |
| Samples above surface exclusion |
The number of samples above the Exclude above line. The Exclude-above line is specified on the Analysis page of the Variable Properties dialog box. May be exported as Samples_above_surface_exclusion. |
| Samples below bottom exclusion |
The number of samples below the Exclude below line. The Exclude-below line is specified on the Analysis page of the Variable Properties dialog box. May be exported as Samples_below_bottom_exclusion. |
| Samples in domain |
The number of samples contained within the region. May be exported as Sample_in_domain. |
|
Pings |
The number of pings between the start and end time of the region. The number of pings is not affected by bad data regions. |
Select Linked to link the displayed results to the currently activated region or selection. The displayed results will update as you select subsequent regions or selections of the echogram.
Note: With Linked selected, the dialog box will respond to the activated region on the Region browser and the Regions window.
