Polarization and radiance profiles of refraction halos were measured as a function of scattering angle. The width of the halo polarization peaks conflicts the observed size distribution of the replicated crystals. This discrepancy can be explained if the interfacial angles are not always exact integer multiples of 60°, but have an average deviation from this value of 0.49° ± 0.05°.
