measurement. In particular, the JES is variated by 2% for $y^{jet}<1.3$ and by 3% for $y^{jet}>1.3$, following [@Khachatryan:2016kdb]. The JER is varied by 20% for $30<{\ensuremath{E_{\mathrm{T}}}}^{jet}<100$ GeV, by 10% for $100<{\ensuremath{E_{\mathrm{T}}}}^{jet}<1$ TeV and by 5% above. The absolute angular $\phi$- and $\eta$-resolution for reconstructed jets with a transverse momentum of 50 GeV is between 0.01 and 0.02 and improves for larger [$p_{\mathrm{T}}$]{} values. We assume a relative uncertainty of 50% on the both angular resolutions.

Events containing exactly two jets with ${\ensuremath{p_{\mathrm{T}}}}>50$ GeV within $y^{jet}<2.4$ are used to test the calibration as well as the assigned uncertainties. A comparison of the ${{\Delta^{\text{rel}} _{{\ensuremath{p_{\mathrm{T}}}}}}}= ( {\ensuremath{p_{\mathrm{T}}}}^{j_{1}}-{\ensuremath{p_{\mathrm{T}}}}^{j_{2}})/( {\ensuremath{p_{\mathrm{T}}}}^{j_{1}}+{\ensuremath{p_{\mathrm{T}}}}^{j_{2}})$ distributions for data and MC, including the assigned systematic uncertainties is shown in Figure \[fig:JetPerformance\], where agreement between data and MC can be seen.
