Distribution of intensity observations of a single reflection for lysozyme crystal structure (36, 18, 8). (a) Friedel pairing of CR data. (b) Bijvoet pairing of CR data. (c) Friedel pairing of IBG data. I(+) and I(−) observation pairs are represented as blue dots and posterior density of the mean [F(+)2, F(−)2] location parameters of the multivariate normal distribution is represented by red contour lines (arbitrary units). Each MCMC sample of the joint posterior distribution is represented by a transparent 95% isodensity ellipse, which gradually adds up to darker and darker grey. The length and direction of the ellipse axes are determined from the diagonalized covariance matrix of each MCMC trace sample.
