Abstract
- 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.
