The On-line Brief Teaching Edition of Patterson Peaks includes selected tables of Patterson map peaks (positions and multiplicities) calculated for a unique atom in the general position, for a unique atom in each special position, and for two unique atoms in all possible combinations of positions for the same set of space groups and origin and axis choices as in the Brief Teaching Edition of Volume A of International Tables for Crystallography (1988). The tables, below, have been taken directly from the printed version of Patterson Peaks, which has been published by and is now available through Polycrystal Book Service.
