R(|0FT|) = 0.152	〈Δ(Δφ)〉 = 31.89°	〈m〉 = 0.97
R(|0FA|) = 0.343	〈σ(Δφ)〉 = 10.84°

Values shown are for data between 15.0 and 3.2 Å. R = Σ_hΣ_i∥F_i(h)| − 〈|F(h)|〉|/Σ_h|F(h)|. ⁰F_T(h) is the structure factor due to normal scattering from all the atoms. ⁰F_A(h) is the structure factor due to normal scattering from the anomalous scatterers only, and Δφ(h) is the phase difference between ⁰F_T(h) and ⁰F_A(h). Δ(Δφ) is the difference between independent determinations of Δφ(h) = ⁰ϕ_T − ⁰ϕ_A.
