  An experimental procedure is proposed to perform measurements of differential
cross sections which can be compared to fixed-order QCD predictions with
improved accuracy. The procedure can be applied to the Drell-Yan cross-section
measurements which are differential in the boson transverse momentum. An
example analysis is performed using the ATLAS measurement of the $Z$-boson
production cross section at center-of-mass energy of $8$ TeV. The resulting
full phase space measurement of the cross section differential in the boson
rapidity is compared to theoretical predictions computed with next-to-next-to
leading-order accuracy in QCD.
