Description
Residual factor R(Fsqd) 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, calculated on the squares of the
observed and calculated structure factor amplitudes.

R(Fsqd) = ---------------------------
sum|F~obs~^2^|
F~obs~^2^ = squares of the observed structure factor amplitudes
F~calc~^2^ = squares of the calculated structure factor
amplitudes
sum is taken over the specified reflections
