Subtracting the amorphous content from the crystalline pattern requires a weightfactor,
which is empirically set by equating the maximum of the amorphous halo
to the minimum between the E
FG and the E
+AFG diffraction peaks. The shaded
region in Fig. 2.2 shows the weighted amorphous region. The resulting pattern
after subtraction is given in Fig. 2.3 (Burgt van der et al. (2002)).
