Figure 7
Quality of the phases obtained by exploiting the AAS-induced symmetry-breaking effects in d(CGCG[BrU]G). The plots represent the correlation coefficients, as a function of resolution, of maps computed from experimental phases with a map computed from the final refined structure of d(CGCG[BrU]G). All three data sets (crystal orientations) have been used for phasing. Black, SAD phases computed from merged data with conventional isotropic f′′ factors. Red, phases computed from unmerged data using a tensorial description (f′′) for the imaginary anomalous scattering factors (see Table 2[link]). Green, phases computed from unmerged data using distinct f′′ factors for `symmetry-unrolled' sites and for each data set (see Table 3[link]).
