Crystallographic statistics

Low completeness values reflect the fact that an elliptical mask was applied prior to scaling was used to accommodate highly anisotropic diffraction data (Lodowski et al., 2003). Without the mask, data had 82.4% overall completeness and 82% in the highest resolution shell for 4MK0 and 100% overall completeness and 100% completeness in the highest resolution shell for 4L9I.
