Definition:
Fraction of crystal point-group unique reflections (i.e. symmetry-independent in the crystal point group) measured out to the resolution given in _diffrn_reflns_resolution_max or _diffrn_reflns_theta_max. For space groups that do not contain a centre of symmetry the reflections h,k,l and -h,-k,-l are independent.
