Definition:
Residual factor R for reflections that satisfy the resolution
limits established by _refine_hist.d_res_high and
_refine_hist.d_res_low.
sum|F~obs~ - F~calc~|
R = ---------------------
sum|F~obs~|
F~obs~ = the observed structure-factor amplitudes
F~calc~ = the calculated structure-factor amplitudes
sum is taken over the specified reflections
