Arguments
depth
depths of samples within pings
src
optional string indicating data source
sourceLevel
source level, in dB (uPa at 1m), denoted sl in [1
p15], where it is in units 0.1dB (uPa at 1m)
receiverSensitivity
receiver sensivity of the main element, in
dB(counts/uPa), denoted rs in [1 p15], where it is in units of
0.1dB(counts/uPa)
transmitPower
transmit power reduction factor, in dB, denoted
tpow in [1 p10], where it is in units 0.1 dB.
pulseDuration
duration of transmited pulse in us
beamwidthX
x-axis -3dB one-way beamwidth in deg, denoted bwx
in [1 p16], where the unit is 0.2 deg
beamwidthY
y-axis -3dB one-way beamwidth in deg, denoted bwx
in [1 p16], where the unit is 0.2 deg
frequency
transducer frequency in Hz, denoted fq in [1 p16]
correction
user-defined calibration correction in dB, denoted
corr in [1 p14], where the unit is 0.01dB.
