"Table 1" of "Combination of Measurements of Inclusive Deep Inelastic $e^{\pm}p$ Scattering Cross Sections and QCD Analysis of HERA Data"

HERA combined reduced cross sections $\sigma_{r,\rm NC}^{+}$ for NC $e^{+}p$ scattering at $\sqrt{s} = 318$ GeV;
$\delta_{\rm stat}$, $\delta_{\rm uncor}$ and $\delta_{\rm cor}$ represent the statistical, uncorrelated systematic and correlated systematic uncertainties, respectively;
$\delta_{\rm rel}$, $\delta_{\gamma p}$, $\delta_{\rm had}$ and $\delta_{1}$ to $\delta_{4}$ are the correlated sources of uncertainties arising from the combination procedure.
The uncertainties are quoted in percent relative to $\sigma_{r,\rm NC}^{+}$.

HERA合作组测得的中性流（NC）e⁺p散射在质心系能量√s=318 GeV下的组合约化截面σ_{r,NC}^+；δ_stat、δ_uncor和δ_cor分别代表统计不确定性、非关联系统不确定性和关联系统不确定性；δ_rel、δ_γp、δ_had以及δ₁至δ₄是组合过程中产生的关联不确定性来源。所有不确定性均以相对于σ_{r,NC}^+的百分比形式给出。
