Figure 8
Graph showing several R-factors and data completeness (C) with respect to resolution. Rm is the standard merging R-factor on intensities, Rx is the conventional R-factor for the final model, calculated using X-PLOR (Brunger, 1992BB2), Rav is the R-factor between the observed structure factor amplitudes and those derived from inversion of the averaged solvent-flattened map, 〈I〉/〈σ(I)〉 is the mean standard intensity divided by the mean error estimated by SCALEPACK (Otwinowski & Minor, 1997BB16). Note how the averaging and refinement R-factors are notably better than R-merge, indicating that there is useful information in seemingly poor-quality data.
