15. The average base line of the PM-RD values is not at the zero level but is found to have a negative value. This comes from, for example, polarization artifacts of the PEM and the optical setup. The amplitude of the PM-RD signal, however, is hardly affected by such artifacts (Ref. and M. Schmidt, to be published), hence it is a suitable indicator of the sample anisotropy irrespective of the experimental artifacts.

17. The angle-dependent PM-RD values can be fitted by a well-defined formula, as shown in Ref., where the parameters used for the fitting were found to be consistent with the reflectivities shown in Figs. 1 1, with the reflectivity difference of, e.g., ∼10% at 8°C for the domain A.
