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. sum|Fobs - Fcalc| R = --------------------- sum|Fobs| Fobs = the observed structure-factor amplitudes Fcalc = the calculated structure-factor amplitudes sum is taken over the specified reflections
