Data type: numb (with optional s.u. in parentheses)
Units: e_A^-3^ ( electrons per cubic angstrom)
The largest, smallest and 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.
