Ratios $v_2$(Ne--Ne/OO) and $v_3$(Ne--Ne/OO) as a function of centrality in the 0–30\% centrality range. The vertical lines represent statistical uncertainties and the open boxes represent the systematic uncertainties, while most of them are smaller than the symbol size. The measurements are compared with Trajectum calculations with NLEFT and PGCM inputs  as well as IP-Glasma+JIMWLK+MUSIC+UrQMD  and 3DGlauber+MUSIC+UrQMD  calculations with PGCM input.
