"Figure 6a (2)" of "Measurement of the azimuthal anisotropy of charged particles in $\sqrt{s_{\mathrm{NN}}}=5.36$ TeV $^{16}$O$+^{16}$O and $^{20}$Ne$+^{20}$Ne collisions with the ATLAS detector"

(a) Flow harmonics v_n^sub{2} and v_n{4} for the elliptic and triangular moments in O+O collisions (colored solid markers) and Ne+Ne collisions (open black markers) at √s_NN=5.36 TeV, shown as a function of N_ch. The Ne+Ne points are slightly displaced along the horizontal axis for visual clarity. (b) Ratios of the flow coefficients in Ne+Ne to those in O+O collisions, corresponding to the results in panel (a). Ratios are shown only for the 0–50% centrality range to suppress large statistical fluctuations in more peripheral intervals. The vertical lines and vertical bars indicate statistical and systematic uncertainties, respectively. For the ratios, systematic uncertainties correlated between the O+O and Ne+Ne measurements largely cancel.
