Distributions of relevant characteristics of data sets in the database. The vertical axes represent kernel density distribution. (a) Distribution of resolution limits; data to worse than 4 Å resolution were excluded. (b) Distribution of wavelengths. (c) Distribution of total anomalous scattering for the reference substructures, corresponding to the number of fully occupied anomalous scatterers with equivalent scattering power. This is measured as the f′′-weighted sum of squared occupancies of refined sites to account for both primary and secondary anomalous scatterers. (d) Distribution of refined f′′ values after the log-likelihood-gradient completion protocol. (e) Distribution of correlation coefficients between the experimentally phased map at the end of the log-likelihood-gradient completion protocol and density corresponding to the deposited model. (f) Distribution of molecular weights of the target proteins. |
