Context
The calibration process uses a sphere with a specific diameter and of a specific material which yields a known target strength. During the calibration process the known target strength is used as a reference to adjust the actual target strength values
obtained. When data is collected, you may also acquire “hits” from other targets in the sea. Such targets could be fish or objects in the water column, or simply the result of noise.It is advantageous to delete such erroneous hits, as these would have a negative effect on the calibration accuracy.
Clicking on a target in the Suspend mode will mark this target in pink colour, and exclude it from all calculations. The suspended target will remain in the data set, and it can be “unsuspended” by clicking on it one more time.
