What is it about?

Nowadays, X-ray diffraction patterns are produced with digital diffractometer, any XRD peak is actually described by a series of data diffraction angles and intensities. There exist errors produced from goniometer and X-ray emission, therefore those pair angles and intensities need to be corrected. Data smoothing is the way to reduce the error level of those pair data. How can we do? Correcting equations are proposed based on the assumption mathematic function being of the perfect shape of an XRD peak.

Why is it important?

To reduce the error level of data and to approach the nature of an XRD peak will benefit of the studies using X-ray diffractometry.

Perspectives

It is hope, with this article, people understand no hard smoothing will save your data shifting away from the nature of an XRD peak.
