Modulated and composite structures dictionary (msCIF) version 1.0.1
Data items in the CELL_WAVE_VECTORS category record details about the set of independent modulation wave vectors q~i~ and their measurement. The diffraction vectors are indexed in the form ha*+kb*+lc*+sum~i~ (m~i~q~i~). sum~i~ is taken over all wave vectors. In this version of the dictionary, the index i has been restricted to be less than 9.Example:
Example 1 - example corresponding to the one-dimensional incommensurately
modulated structure of K~2~SeO~4~.
