_refine.pdbx_pd_Fsqrd_R_factor

Name:
'_refine.pdbx_pd_Fsqrd_R_factor'

Definition:

   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|F~obs~**2 - F~calc~**2|
        R = ---------------------
                 sum|F~obs~**2|
        F~obs~  = the observed structure-factor amplitudes
        F~calc~ = the calculated structure-factor amplitudes
        sum is taken over the specified reflections
