σ(2) (R), a reciprocal-space measure of the quality of macromolecular electron-density maps
It has previously been shown that the presence of distinct regions of solvent and protein in macromolecular crystals leads to a high value of the standard deviation of local r.m.s. electron density and that this can in turn be used as a reliable measure of the quality of macromolecular electron-dens...
