Details dialog box

The Details dialog box displays details about:

  • the sample under the mouse pointer in an echogram window or cruise track window
  • the dataflow object under the mouse pointer in the Dataflow window
  • the fileset and data file information under the mouse pointer in the Filesets window

Use the Shortcut menu > Select All and Copy to take the information to your favorite text editor.

To display the Details dialog box:

Click View to show or hide types of details. Use Expand/Collapse controls to change the display of details.

Notes:

  • The Target (from file) category is displayed for single target data and converted multibeam target data.
  • Some data types may display empty (but potential) category headings.
  • Some details may be absent from data files and as a result will not be displayed.
  • The state of the Expand/Collapse controls are remembered for a window. However, the correlation between mouse pointer, the intended window and the Details section can become lost or incorrect when the mouse pointer travels across other windows or Messages window to the Details window.

To select the number of decimal places (DP) to display for the depth and range in the Details dialog box

  1. Click View, select Display precision.
  2. In the Display precision box, select the desired decimal places (DP) to display.

This value may be useful as a diagnostic to identify variables that are slow to compute ping data.

(Several factors contribute to how long it takes to calculate a ping. Examples include the complexity of the algorithm or if the data is cached.)

Generations

The ping generation statistic (count). Pings are generated in Echoview on demand; for example, when an echogram is displayed or data is exported. The statistic can be used to set the ping cache limits to optimize your processing performance.

+ Target property from single beam data.

* Target property from multibeam data.

#Single target pulse properties.

Notes:

  • #The target's TS value and often identical to TS_comp. The type of single target detection algorithm and the beam compensation used by the algorithm affect how the target TS value is evaluated and affect how the export variables TS_uncomp and TS_comp are evaluated. Check the relevant single target detection algorithm for details.
  • Depth is single target True_depth.

Target (from file)

File added to the fileset. This file contains multibeam target data in an Echoview single target data format. Such a file is commonly used to improve performance when working with multibeam targets.

Ping (from file)

Ping details pertinent only to the data file which contains the data point to which the mouse points. Different data files in the same fileset may have different settings. Echoview displays some of these values for your information only and uses other values in calculations and to adjust the data that are displayed on the echogram.

Ping tilt (H-mode and S-mode) and bearing (V-mode and S-mode) angles (refer to About ping modes) are shown for supported multibeam file formats.

Note: If a parameter also appears on the Calibration page of the Variables properties dialog box, Echoview does not automatically use the value displayed under Ping (from file). You must manually enter the value you want Echoview to use on the Calibration page of the Variables properties dialog box.
