26. PA was optimized by satisfying the normalization constraints and takes the value 85 monomers per copolymer chain.

The counterion structure factor is unaffected by a small, residual scattering from the PA-block density correlations, since the former is obtained from the modulation of the intensities with contrast variation in TMA. However, the PA contributes to the PS involved structure factors to an insignificant degree.
28. Note that the structure factors are normalized, and factors related to the counterion and polyelectrolyte block concentrations have been accounted for.
