Item Description

Residual factor R for reflections that satisfy the resolution limits established by _refine.ls_d_res_high and _refine.ls_d_res_low and the observation limit established by _reflns.observed_criterion. sum|Fobs**2 - Fcalc**2| R = --------------------- sum|Fobs**2| Fobs = the observed structure-factor amplitudes Fcalc = the calculated structure-factor amplitudes sum is taken over the specified reflections
