Left: ${C \left(\Delta \phi \right)}$ for particle pairs at $|{\Delta\eta}| > 0.8$. The Fourier harmonics for $V_{1\Delta}$ to $V_{5\Delta}$ are superimposed in color. Their sum is shown as the dashed curve. The ratio of data to the $n \leq 5$ sum is shown in the lower panel. Center: Amplitude of ${V_{n\Delta}}$ harmonics vs.\ $n$ for the same ${p_{T}^{t}}$, ${p_{T}^{a}}$, and centrality class. Right: ${V_{n\Delta}}$ spectra for a variety of centrality classes. Systematic uncertainties are represented with boxes (see section 4 Factorization and the global fit), and statistical uncertainties are shown as error bars. | ![](https://alice-publications.web.cern.ch/sites/default/files/papers/3504/dphiFourier_RIDGE_cent0to2_pTtrig2to2.5_pTassoc1.5to2_color-27137.png ) ![](https://alice-publications.web.cern.ch/sites/default/files/papers/3504/VnDeltaVsN_ptt2to2.5_pta1.5to2_cent02_nobars-27138.png ) ![](https://alice-publications.web.cern.ch/sites/default/files/papers/3504/VnDeltaVsN_ptt2to2.5_pta1.5to2_nobars-27139.png ) |
