Context
The calibration procedure will result in adjusting a set of coefficients. These coefficients are in turn used when processing target strength data in order to get a correct and as optimum result from
surveys as possible. The gain adjustments is calculated for each beam in the swath. By using the Beam Directions Plot you will see gain adjustments in a colour representation which makes it easier to locate beams where the gain adjustment
has been significantly different from the other beams. These will have a deviant colour. The gain adjustment is also displayed in the Numerical View information field in the Results tab. This is a purely numerical display. Such erroneous results may occur due to disturbances during calibration such as jellyfish, fish or other and will in turn
affect the target strength calculations in surveys.
