pSEOBNRv5HM and pSEOBNRv5PHM - integration of GR deviations
Adds the parametrized model pSEOBNRv5HM and pSEOBNRv5PHM. Specifically, it allows adding parameterized deviations to:
- QNM frequency and damping time for each mode. For the 32 (43) mode, which feature mode mixing, the corrections come both from the 320 and 220 (430 and 330) spheroidal modes. In the precessing case, the deviations are applied to the J-frame frequencies, and the rotation to the co-precessing frame (Eq. 34 of arXiv:2301.06558) is applied after the correction is applied.
- Amplitude and frequency at merger for each mode, as in https://arxiv.org/abs/2212.09655. In the precessing case, the deviations are applied to the co-precessing frame modes.
- Merger time, via
NR_deltaT
(time difference between the remnant rISCO and the peak of the 22 mode). For now the same correction as https://arxiv.org/abs/2212.09655 is applied, but since the parameter is not the same as SEOBNRv4 (in which it was the time difference between the peak of the orbital frequency and the peak of the 22 mode), one might try other possibilities. - Calibration parameters
a_6
andd_{SO}
in the EOB Hamiltonian. - Adds the possibility of specifying the ODE/PA integration tolerances (see Appendix A of https://arxiv.org/abs/2307.15086, this is helpful to use the model for very high SNR signals).
To use the model with the gwsignal
waveform interface, minor changes to lalsuite done in this branch are needed to allow for the extra non-GR parameters.
An extension of the bilby
gwsignal_binary_black_hole
source class with parametrized deviations is also available in this branch of bilby_tgr
.
