Figure 5
Model of the experimental uncertainties. The left panel depicts the graph of I/σ(I) versus (I) for the 1fm4 data set (i.e., a subsection of a non-log Diederichs plot). The distribution follows the I1/2 versus I parabola (a.k.a. power law), indicating that the σs are derived without limiting experimental errors from I(calc) or F(calc). Adding random noise as described in the text yields an error distribution (right panel) that closely resembles that of the deposited data (left panel).
