A new study of the sigmaA parameter has been undertaken to understand its behaviour when the diffraction amplitude distributions are far from the standard Wilson distributions. The study has led to the formulation of a new statistical interpretation of sigmaA, expressed in terms of a correlation factor. The new formulas allow a more accurate use of sigmaA in electron-density modification procedures.

Abstract
A new study of the sigmaA parameter has been undertaken to understand its behaviour when the diffraction amplitude distributions are far from the standard Wilson distributions. The study has led to the formulation of a new statistical interpretation of sigmaA, expressed in terms of a correlation factor. The new formulas allow a more accurate use of sigmaA in electron-density modification procedures.File in questo prodotto:
