Luzzati Plot

The $R$ value as a function of resolution and intensity can be obtained by issuing the PRINt R statement after structure factors have been computed. The output of the PRINt R statement can be used to make a plot of the $R$ value distribution, the so-called Luzzati plot (Luzzati, 1952). In the following example, the X-PLOR script file creates a file “luzzati.list":

luzzati.inp

The following Mathematica script can be used to make the Luzzati plot shown in Fig. 13.1:

luzzati.math
