We report application of a method for extracting gravitational waves tothree-dimensional numerical simulation on coalescing binary neutron stars. Wefound the extracted wave form includes the componets corresponding to thequadrupole part in the Newtonian potential of the background metric, if it ismonitored at a position not far from the central stars. We present how toeliminate it.Comment: 6 pages, 5 figure
