The incident energy at which the azimuthal distributions in semi-central heavy ion collisions change from in-plane to out-of-plane enhancement is studied as a function of mass of emitted particles, their transverse momentum and centrality for Au+au collisions. The analysis is performed in a reference frame rotated with the sideward flow angle relative to the beam axis.
