Comparison of total $\langle $d$E_{\mathrm T}/$d$\eta \rangle / \langle N_{\mathrm{part}}/2 \rangle$ versus $\langle N_{\mathrm{part}} \rangle$ at midrapidity using tracking detectors, using EMCal+tracking, using PHOS+tracking, and as calculated from the measured particle spectra. The boxes indicate the systematic uncertainties.
