Item Description
For each reflection class, the residual factor for significantly
intense reflections (see _reflns.threshold_expression) included
in the refinement.
The reflections also satisfy the resolution limits established by
_refine_ls_class.d_res_high and _refine_ls_class.d_res_low.
This is the conventional R factor. See also the definition of
_refine_ls_class.wR_factor_all.
sum | F(obs) - F(calc) |
R = ------------------------
sum | F(obs) |
F(obs) = the observed structure-factor amplitudes
F(calc) = the calculated structure-factor amplitudes
and the sum is taken over the reflections of this class.
