The estimation of two-phase and three-phase invariants inP1 when anomalous scatterers are present
Carmelo Giacovazzo · Acta Crystallographica Section A Foundations of Crystallography · 1983
The method of joint probability distributions is applied for the estimation of two-phase and three-phase invariants when anomalous scatterers are present. The conclusive formulae are von Mises functions and give expected values of the phases lying anywhere between 0 and 2π without ambiguity.
