Summary

Abstract

High volume echo data file. Three data blocks are written into this file every ping; the pelagic echogram block, the bottom echogram block, and the echotrace block.

Entity Information

Data Attribute / Type Description
PelagicData
Text 		Copied from the received EK500 echogram (Ql, Q2, Q3) telegrams. Both data blocks are arrays of volume backscattering strength coefficients. The coefficients are stored in the EK500 dB format.
BottomData
Text 		Copied from the received EK500 echogram (Ql, Q2, Q3) telegrams. Both data blocks are arrays of volume backscattering strength coefficients. The coefficients are stored in the EK500 dB format.
TargetDepth
Float 		Target depth in meter.
CompTS
Float 		Estimated target strength in dB with and without transducer pattern compensation.
UncompTS
Float 		Estimated target strength in dB with and without transducer pattern compensation.
Alongship
Float 		Target directional angles in degrees
Athwartship
Float 		Target directional angles in degrees
