Comparison of the measured track isolation (left) and calorimeter isolation (right) distributions of the probe muon (from $Z$ decays) with the Monte Carlo predictions, for two different cone sizes using the isolation variables defined in the text. The upper and lower plots correspond to $\mathrm{\Delta }R=0.4$ and $\mathrm{\Delta }R=0.3$, respectively. The simulation includes the effects of pile-up, as described in the text. The uncertainties are statistical
