Figure 4
Consistency between I and σ. Weighted second moments of the acentric reflections for (a) thermolysin, (b) cytochrome, (c) IPNS, (d) MMOH and (e) sMMOox as a metric to evaluate the uncertainty estimates of the error model. According to Wilson's distribution, the second moment of the intensities of an acentric reflection for a nontwinned crystal should be two, as shown by the solid gray line. At high resolutions, where the uncertainty in the intensity becomes comparable to the mean intensity, the second moment should increase from two. This deviation is calculated from the estimated uncertainties and is shown as dotted lines for the Ev11 (blue) and MM24 (pink) protocols. The solid colored lines show the observed second moment calculated from the intensities of the reflection. |
