Legend

s = the sensor number

t = the transducer number

n = the channel number

H = H-mode pings

V = V-mode pings

Notes:

Simrad is a subsidiary of Kongsberg. See also Raw variables derived from Kongsberg data files.
The variables that are derived from any given data file will depend on the transducer type and transducer calibration used during logging.
Vessel logs can be derived from some data files. They can be:
- used as the source of distance for time/distance grids,
- used as the source of distance for school detection, and
- included in exported data, see About analysis variables.
Sv raw pings, TS raw pings and angular position raw pings may all be multiplexed by users with specific hardware. Multiplexed variables will have (channel c) appended to their name - where c is the channel number. See Multiplexed variables.
