• Relativistic heavy ion collision
• reaction plane detector

We have measured azimuthal anisotropy of neutral pion in root S-NN = 200 GeV Au+Au collisions at Relativistic Heavy Ion Collider (RHIC). In 2007, we have installed a new detector to measure reaction plane of collisions more precisely. This new detector is called reaction plane detector (RxNP). We report the results for azimuthal anisotropy of neutral pion for each 3 centrality steps. The determination of reaction plane achieved twice better resolution than Year-2004 run.
