Figure 6
Plot of Iobs/σ(Iobs) versus resolution for PDB entry 4epz. (a) At high resolution ice rings are clearly visible, while at low resolution the values are clustered, forming a `ladder-like' scatter plot. (b) The same plot coloured by multiplicity. The higher the multiplicity the larger Iobs/σ(Iobs) is, thus accounting for the behaviour. The value of a measurement is less uncertain the more often it has been made, as shown for example by Watkin & Cooper (2016BB29). At low resolution, the main influence on these values is their multiplicity. In contrast, at high resolution weaker reflections are influenced by other factors.
