Comparsion is not straightforward because: |
| |
- Initial conditions for the NR simulations are not completely known
- Have to split hybrid waveforms so get only the NR part
- There could be (is) a phase shift between the waveforms that has to be checked / modified
|
| |
- The inclusion of all the PN contributions is important
- The use of the BT gauge provides results similar to NR data
- With the appropriate change of the coordinates the results in the BT and DD gauges can be transformed to each other

- Unphysical behaviour is excluded if one takes into account the domain of validity of PN and the requirements for energy conservation

- Anomalies are excluded if one takes into account the domain of validity of PN and the requirements for energy conservation
