Length conversion parameters realting different length measurements.
Details
Length conversion factors relating different length measurements, such as 'standard length' and 'fork length' based on a linear regression fit between length measurements: L1 = alpha + beta \* L2, where L1 and L2 are different length measurements and 'alpha' and 'beta' are species-specific coefficients.
