Jerlov Type IA has the values

    absorption   0.655215     0.0603407     0.0268692
    scattering   0.016104     0.019005      0.0210976
    extinction   0.671319     0.0793457     0.0479668
    diffuseK     0.57         0.0556        0.02508
    reflectivity 0.0002       0.014         0.04612

The physical units of the numbers in the first four lines are [1/meter]. The numbers for reflectivity are dimensionless fractions. This choice is suitable for the clear equitorial ocean waters in the world, but not as clear as type I.
