$\Delta_\mathrm{recoil}$ for 0-10% central Pb-Pb collisions at $\sqrt{s_{\mathrm {NN}}}$ = 2.76 TeV for anti-$k_\mathrm{T}$ jets with ${R}$ = 0.2, 0.4 and 0.5. The vertical error bars are the square root of the diagonal elements of the unfolding covariance matrix, with the boxes indicating correlated and uncorrelated (shape) systematic uncertainties.
