'_refine_diff_density_max' '_refine_diff_density_min' '_refine_diff_density_rms'


   The largest and smallest values and the root-mean-square
   deviation, in electrons per angstrom cubed, of the final
   difference electron density. The *_rms value is measured with
   respect to the arithmetic mean density and is derived from
   summations over each grid point in the asymmetric unit of
   the cell. This quantity is useful for assessing the
   significance of *_min and *_max values, and also for
   defining suitable contour levels.
