Abstract

The statistical analysis of the observed structure factor moduli gives very useful indications on the presence or not of those symmetry elements which do not give rise to systematic absences. It also allows to obtain an estimate both of the scale factor by which one has to multiply the measured data to scale them to their absolute value, and of the temperature factor. Finally it is a basic step in the calculation of unitary and normalized structure factors, which will be seen to be useful quantities when using direct methods.
