  • Results in developing two new methods to improve the accuracy of waveform extraction using characteristic evolution.
  • Numerical method: circular boundaries, with angular dissipation in the characteristic code.
  • Geometric method: computation of Weyl tensor component Y4 at null infinity, in a conformally compactified treatment.
  • Comparison and calibration in tests problems based upon linearized waves.
