What is it about?
This is a sequel to the 2009/10 article, with three improvements in computational technique introduced. The implementation of the computer codes on parallel processors of a PC is discussed.
Why is it important?
The replacement of the sine sum by a fast Fourier transform (FFT) brings a significant improvement in computational time, as does the exploitation of crystal symmetry. Further, analytical, rather than discrete probability arguments lead to a better treatment of disordered crystals.
