title: "Table 6" of "Symmetry plane correlations in Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$TeV"

description: Centrality dependence of $\langle \cos[2\Psi_{2}+4\Psi_{4}-6\Psi_{6}]\rangle_{\mathrm{GE}}$ in Pb--Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV.
description: A newly developed observable for correlations between symmetry planes, which characterize the direction of the anisotropic emission of produced particles, is measured in Pb--Pb collisions at $\sqrt{s_\text{NN}}$ = 2.76 TeV with ALICE. This so-called Gaussian Estimator allows for the first time the study of these quantities without the influence of correlations between different flow amplitudes. The centrality dependence of various correlations between two, three and four symmetry planes is presented. The ordering of magnitude between these symmetry plane correlations is discussed and the results of the Gaussian Estimator are compared with measurements of previously used estimators. The results utilizing the new estimator lead to significantly smaller correlations than reported by studies using the Scalar Product method. Furthermore, the obtained symmetry plane correlations are compared to state-of-the-art hydrodynamic model calculations for the evolution of heavy-ion collisions. While the model predictions provide a qualitative description of the data, quantitative agreement is not always observed, particularly for correlators with significant non-linear response of the medium to initial state anisotropies of the collision system. As these results provide unique and independent information, their usage in future Bayesian analysis can further constrain our knowledge on the properties of the QCD matter produced in ultrarelativistic heavy-ion collisions.

These bins were constructed using the corrected finite values as centers.

title: "Figure 1a" of "Suppression pattern of neutral pions at high transverse momentum in Au+Au collisions at sqrt(s_NN) = 200 GeV and constraints on medium transport coefficients"

description: $\pi^0$ invariant yields for different centralities. The bin range is not an uncertainty in the x-axis because the actual uncertainty by having the finite bin width is corrected for by the bin-shift correction. These bins were constructed using the corrected finite values as centers.
description: For Au+Au collisions at 200 GeV, we measure neutral pion production with good statistics for transverse momentum, $p_T$, up to 20 GeV/$c$. A fivefold suppression is found, which is essentially constant for 5 &lt; $p_T$ &lt; 20 GeV/$c$. Experimental uncertainties are small enough to constrain any model-dependent parameterization for the transport coefficient of the medium, e.g. $&lt;\bar{q}&gt;$ in the parton quenching model. The spectral shape is similar for all collision classes, and the suppression does not saturate in Au+Au collisions; instead, it increases proportional to the number of participating nucleons, as $N_{part}^{2/3}$.
