The measured fraction of lost tracks, $F^{{\text{lost}}_{\text{2}}}$, in the jet core ($\mathrm{\Delta }\mathit{R}\text{(jet,trk)}$ $<0.05$) as a function of jet $p_{\text{T}}$ for data (black circles) and simulation (red line). Vertical solid error bars indicate statistical uncertainty, while the total uncertainty is represented by dashed error bars for data and a shaded area for simulation
