Comparison of model-based probabilities with probability distributions from measurement error. (a) Model-based probability distributions for E2c  = 1 and σA values of 0, 0.7, 0.95 and 0.99. The distribution for a σA of zero is equivalent to a Wilson distribution, and as σA increases, the distributions become sharper. (b) Gaussian probability distributions for E2 = 1 and measurement s.u.s of 0.5, 0.2 and 0.1. In other terms, these correspond to 2σ, 5σ and 10σ measurements. (c) Model-based probability distributions for σA = 0.95 and E2c of 0.1, 2 and 4. Calculated structure factors at one extreme are more useful for detecting outliers at the other extreme.
