Arguments

Sv: Observed mean volume backscattering strength (Sv) of a school
L: Observed (uncorrected) school length, m
P: Mean depth of school
Th: Minimum Sv data threshold used to detect schools using the SHAPES algorithm
theta: Transducer 3 dB beam width, degrees

Value

Relative school dimension (Nb)
