Practical Electron Microscopy and Database

As shown in Figure 2496 (for NaCl here), each XRD JCPDS (Joint Committee on Powder Diffraction Standards) card contains the following information:
        ➀ The file number,
        ➁ The three strongest lines,
        ➂ The lowest angle line,
        ➃ The chemical formula,
        ➄ The data on diffraction method used,
        ➅ The crystallographic data,
        ➆ The optical and other data,
        ➇ The data on specimen,
        ➈ The data on diffraction pattern.

It is very common that all the information above is an integral portion of the software coming with the instrumentation.
