_refine_ls_shell.wR_factor_R_work

Name:
'_refine_ls_shell.wR_factor_R_work'

Definition:

   Weighted residual factor wR 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|w |Y~obs~ - Y~calc~|^2^| )^1/2^
   wR = ( ---------------------------- )
        (        sum|w Y~obs~^2^|      )

   Y~obs~  = the observed amplitude specified by
             _refine.ls_structure_factor_coef
   Y~calc~ = the calculated amplitude specified by
             _refine.ls_structure_factor_coef
   w       = the least-squares weight

   sum is taken over the specified reflections
