The κ = 180° section of the self-rotation function calculated for the SeMet peak data set using POLARRFN (Collaborative Computational Project, Number 4, 1994) with an integration radius of 20 Å and data in the resolution range 20–5 Å. The peak (marked with an X) at (φ, ψ) = (70.8, 0°) represents 56.5% of the peak for the crystallographic twofold. |
