Abstract

In this talk I present new STAR results on measurements of integrated elliptic flow at midrapidity in Au+Au and Cu+Cu collisions at $\sqrt{s_{NN}}=$ 200 and 62 GeV energies. These results have been obtained from azimuthal correlations between particles in the main STAR TPC and two forward TPCs, and are to a large extent free from so-called non-flow correlations. These results along with the previously reported values of ``participant'' eccentricity taking into account eccentricity fluctuations are used for testing the $v_2/\eps$ scaling, which is found to hold relatively well.
