(a) Plot of average B factor and real-space difference density Z scores RSZD− and RSZD+ (as defined in §5.8[link]) as a function of residue sequence number for the main-chain atoms (including Cβ) of the 1f83 structure; (b) the same for 3g94; (c) the same for 2w96. The suggested levels of significance (±3σ) are also shown (dotted lines). This shows the much higher frequency of RSZD+ scores above the level of significance for 1f83 and 3g94 compared with 2w96, indicating significant regions of positive density in the difference Fourier corresponding to errors in the models.
