The variance of electron-density maps (observed, difference and hybrid) is estimated in P1 under the hypothesis that the phases are distributed about the correct values according to von Mises distributions.
research papers
A new set of statistical formulas estimating the σA parameter are described and their mean features are studied.
research papers
The variance in any point of the electron-density map is estimated for any space group, whether centric or acentric. Calculations may be performed no matter how poor the structure model.
