The transverse momentum dependence of the azimuthal anisotropy parameter n2, the second harmonic of the azimuthal distribution, for electrons at mid-rapidity (|h| < 0.35) has been measured with the PHENIX detector in Au+Au collisions at Ö(sNN) = 200 GeV with respect to the reaction plane defined at high rapidities (|h| = 3-4). From the result, we have calculated non-photonic electron n2, which is expected to reflect the heavy-flavor azimuthal anisotropy, by subtracting n2 of electrons from other sources such as photon conversions, Dalitz decay etc.
