Ratio of $\mathrm{v}_n\{2\}$ between central ($0$-$5\%$) and peripheral ($50$-$60\%$) events for $\mathrm{v}_2$, $\mathrm{v}_3$ and $\mathrm{v}_4$. The vertical lines represent the statistical uncertainties and the boxes represent the systematic uncertainties. The $\mathrm{v}_2$ results are multiplied by 3 to fit on the same scale as $\mathrm{v}_3$ and $\mathrm{v}_4$. |
