Invariant differential yields of neutral pions produced in Pb-Pb and inelastic pp collisions at $\snn= 2.76 {TeV}$. The spectra are the weighted average of the PHOS and the PCM results. The vertical lines show the statistical uncertainties, systematic uncertainties are shown as boxes. Horizontal lines indicate the bin width. The horizontal position of the data points within a bin was determined by the procedure described in For the pp spectrum a fit with a power law function $1/p_{\rm T}^n$ for $p_{\rm T} >  3 {GeV}/c$ and a Tsallis function (also used in ) are shown. The extrapolation of the pp spectrum provided by the Tsallis fit is used in the $R_{\rm{AA}}$ calculation for $p_{\rm T} \gtrsim  8 {GeV}/c$.
