Simrad Ex60 data (.raw, .ek60, .ek6); Simrad Ex70 .raw data; Simrad EK15 .raw data and Simrad ME70 .raw data details

The Details dialog box lists the following information that is specific to Simrad Ex60 data (*.raw, *.ek60, *.ek6); Simrad Ex70 *.raw data; Simrad EK15 *.raw data and Simrad ME70 *.raw data.

Single beam

Ping from file

Channel ID	Channel ID fields from the data file. This information enables you to match the derived single beam variable to a beam in the derived multibeam variable.
Sound speed	Logged sound speed (m/s)
Transducer draft	Logged transducer draft (m)
Sample interval	Single beam sample interval (s)
Transmit power	Single beam transmit power (W)
Pulse length	Single beam pulse length (ms)
Transducer gain	Single beam transducer gain (dB) This is not displayed for Angle data, see Transducer gain.
Absorption coefficient	Logged absorption coefficient (dB/m) This is not displayed for Angle data.
Sa correction	Single beam Sa correction (dB) Displayed for Sv data only.
Minor-axis steered angle	The ME70 Alongship beam steering angle (degrees) of the beam for the derived single beam variable. Note: Exported EVD data for single beam variables may include steered angles from the first ping.
Major-axis steered angle	The ME70 Athwartship beam steering angle (degrees) of the beam for the derived single beam variable. Note: Exported EVD data for single beam variables may include steered angles from the first ping.
