Table values represent rms(Δ|F|)/rms(|F|), where Δ|F| is the Bijvoet difference at one wavelength (diagonal elements) or of the dispersive difference between two wavelengths (off-diagonal elements). The values in parentheses are the ratios for centric Bijvoet reflections, which would be equal to zero for perfect data; these serve as an estimate of the noise in the anomalous signals.
