_refine_diff.density_rms

Definition:

   
     Root mean square density value in a difference Fourier map.
     This 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.

Type: Real

Definition method:

         If (_diffrn_radiation.probe == "neutron")  _units.code =  "femtometres"
    Else If (_diffrn_radiation.probe == "electron") _units.code =  "volts"
    Else                                            _units.code =  "electrons"
