a, \(\langle {v}_{2}^{2}\rangle \) versus \(\delta {p}_{{\rm{T}}}/\langle [{p}_{{\rm{T}}}]\rangle \) in 0–0.5% most central Au + Au and U + U collisions. b, \({\rho }_{2}=\langle {v}_{2}^{2}\delta {p}_{{\rm{T}}}\rangle /(\langle {v}_{2}^{2}\rangle \sqrt{\langle {(\delta {p}_{{\rm{T}}})}^{2}\rangle })\) across centrality, quantifying the strength of v2–δpT correlation. The elliptic-shaped overlaps in the transverse plane for various centralities are also shown.
