Estimation of signal size. The expected Bijvoet diffraction ratio r.m.s.(ΔF±)/r.m.s.(|F|) ≃ (NA/2NT)1/2(2[f''_{A}]/Zeff). The expected dispersive ration r.m.s.(ΔFΔλ)/r.m.s.(|F|) ≃ (NA/2NT)1/2[[f''_{A}](λi) − [f''_{A}](λj)|]/Zeff). NA is the number of anomalous scatterers, NT the total number of atoms in the structure and Zeff is the normal scattering power for all atoms (6.7 e at 2θ = 0).
