Item Description

Residual factor R for reflections that satisfy the resolution limits established by _refine_ls_shell.d_res_high and _refine_ls_shell.d_res_low and the observation limit established by _reflns.observed_criterion, and that were used as the working reflections (i.e. were included in the refinement) when the refinement included the calculation of a 'free' R factor. Details of how reflections were assigned to the working and test sets are given in _reflns.R_free_details. sum|F_obs - F_calc| R = --------------------- sum|F_obs| F_obs = the observed structure-factor amplitudes F_calc = the calculated structure-factor amplitudes sum is taken over the specified reflections

               Residual factor R for reflections that satisfy the resolution
               limits established by _refine_ls_shell.d_res_high and
               _refine_ls_shell.d_res_low and the observation limit
               established by _reflns.observed_criterion, and that were used
               as the working reflections (i.e. were included in the
               refinement) when the refinement included the calculation of
               a 'free' R factor. Details of how reflections were assigned
               to the working and test sets are given in _reflns.R_free_details.
