_refine_ls_F_calc_precision

Name:
'_refine_ls_F_calc_precision'

Definition:

   This item gives an estimate of the precision resulting
   from the numerical approximations made during the evaluation
   of the structure factors using the expression given in
   _refine_ls_F_calc_formula following the method outlined
   in _refine_ls_F_calc_details.  For X-ray diffraction the
   result is given in electrons.


The permitted range is 0.0 -> infinity

Type: numb
