v2(pT) peaks at ~ 3 GeV/c, finite at ~10 GeV/c, strongest for 40-50% centrality
The different methods show differences consistent with the expected sensitivity to non-flow

Integral v2 increases with centrality reaching a maximum at the 40-50% centrality
CMS and ALICE data are in the agreement (except in most peripheral events)

v2 slowly decreases from mid-rapidity to forward rapidity
Stronger rapidity dependence is observed for the most peripheral collisions
