Probability distribution of Bijvoet differences. II

The earlier theoretical treatment of the probability distribution of Bijvoet differences [Parthasarathy & Srinivasan (1964). Acta Cryst. 17, 1400-1407], has been extended to four new situations, namely, when the non-anomalous scatterers (Q) take up centrosymmetric configuration with the anomalous scatterers (P) corresponding to P = one, P = two, P = many atoms with centrosymmetric (MC) and P = many atoms with non-centrosymmetric (MNC) configuration. The theoretical distributions have been verified with hypothetical models.
