Various quality criteria of the cg12ano data set. (a) Dependence between signal-to-noise ratio, I/σ(I), and intensity, I, of all reflections. (b) Values of R
merge (red and green) and χ2 (blue and yellow) as a function of resolution resulting from treating Friedel mates as equivalent (green and yellow) or independent (red and blue) reflections obtained from SCALEPACK. (c) Anomalous signal to noise, ΔF/σ(ΔF), (blue) and CC1/2(ano) (red) values in resolution bins. The dashed lines show the significance levels of these parameters.
