"Table 58" of "Precision measurement and interpretation of inclusive $W^+$, $W^-$ and $Z/\gamma^*$ production cross sections with the ATLAS detector"

Correction factors estimated from Powheg+Pythia6+Photos samples, c.f. Section 2.2, to convert the differential common fiducial central $Z/\gamma^* \to \mu\mu$ cross-section measurements from Born QED level, c.f. Section 6.1.2, to a "dressed" and "bare" QED FSR definition. The "dressed" level is obtained from the charged final-state lepton(s) combined with all FSR photons within a cone R, as defined in Footnote 1, of R<0.1. The "bare" level is obtained from the charged final-state lepton(s) after QED FSR losses. The factors $C_{dressed}$ ($C_{bare}$) are defined as the ratio of the dressed (bare) to the Born QED level cross sections. The statistical uncertainties (stat) are given.
