Calculation of x-ray diffraction from 1d disordered system by means of analytical formulae from Kopp et al. Acta Cryst. (2012) Scattering factor of an atom is calculated using the following the data from:

• D. Waasmaier & A. Kirfel Acta Cryst. (1995). A51, 416-413.
• S. Brennan and P.L. Cowan (1992), Rev. Sci. Instrum. 63, 850.
• Henke, B.L.; Gullikson, E.M.; Davis, J.C. X-ray interactions: photoabsorption, scattering, transmission, and reflection at E=50-30000 eV, Z=1-92, Atomic Data and Nuclear Data Tables, July 1993, vol.54, (no.2):181-342.
