_cell_wave_vectors_[ms]

Name

'_cell_wave_vectors_[ms]'

Category: category_overview

Data type: null

Examples:

     _cell_wave_vectors_meas_details          'Determined from profiles along q'

Example 1 - example corresponding to the one-dimensional incommensurately modulated structure of K~2~SeO~4~.

Definition

    	
   Data items in the CELL_WAVE_VECTOR 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.
