Figure 7
PFW-fyo12e. Square root of weights versus [1/\sigma (F_{\rm o}^2)] plots for refinement regimes (a), (b) and (c). The green lines are unit gradients. (a) corresponds to simple statistical weights. In (b) the weights have been rescaled to give a GoF of unity. The gradient of the observations is 0.2. In (c) the weights are determined from 1/w ≃ σ2(F2) + 0.29F2 + 0.002F4 (SHELX-type weights). The blue line in (c) is drawn at the same gradient (0.2) as the data in the rescaled weights.
