Figure 7
The fourth acentric moments of E, the normalized structure factors, versus resolution for data sets (a) 4puc, (c) 4ef1 and (e) 4kw2. The red line indicates the default background algorithm and the blue line indicates the new global background-model algorithm. The expected value for untwinned data is shown by the theoretical curve in black. The Rfree versus resolution for data sets (b) 4puc, (d) 4ef1 and (f) 4kw2. The red line indicates the default background algorithm and the blue line indicates the new global background-model algorithm.
