摘要：
A recently described probabilistic approach [Giacovazzo (1991). Acta Cryst. A47, 256-263; Altomare, Cascarano & Giacovazzo (1992). Acta Cryst. A48, 30-36] is aimed at integrating information contained in Patterson peaks with direct-methods procedures. The approach is here extended to the information contained in Harker sections. It is also shown that, when heavy atoms are present, the structure seminvariants can be readily estimated by a combination of the so-called symmetry function with a special least-squares procedure.
