Data type: null
Example 1 - based on data set TOZ of Willis, Beckwith & Tozer [(1991). Acta Cryst. C47, 2276-2277].
Data items in the DIFFRN_RADIATION_WAVELENGTH category describe the wavelength of the radiation used in measuring diffraction intensities. Items may be looped to identify and assign weights to distinct wavelength components from a polychromatic beam.
