Measurability of Bijvoet differences in triclinic, monoclinic and orthorhombic crystals. II

The probability that the Bijvoet ratio X for the observed reflections of a given crystal is greater than any particular value X₀ depends on space-group symmetry, the number of anomalous scatterers per asymmetric unit and the parameters k and σ²₁. Numerical values for this probability are obtained as a function 2 for the triclinic, of X₀ for different values of k and σ²₁ monoclinic and orthorhombic crystals containing p (= 1, 2, 3 or 4) anomalous scatterers per asymmetric unit. These results are provided in the form of compact tables; Fortran programs that are useful in computing this probability for any given situation are also provided.
