SEOBNRv4HMROM: automatic hybridization of ROM with TaylorF2
Extension of the SEOBNRv4HM_ROM model to lower frequencies by automatically hybridizing against multi-modal TaylorF2 waveforms. The hybridized model supports can be used as a non-tidal base waveform for low mass binaries such as binary neutron stars and neutron-star black holes.
API Changes and Justification
Backwards Compatible Changes
- This change introduces no API changes
- This change adds new API calls
The new functions
XLALSimIMRSEOBNRv4HMROMFrequencySequence_Modes provide access to waveform polarizations or modes at user specified frequencies as needed to support ROQs.
Backwards Incompatible Changes
- This change modifies an existing API
bool use_hybridization to switch hybridization of the ROM with TaylorF2 on or off.
These functions are not intended to be called by users, although they can be. Users should call
XLALSimChooseFDWaveform instead which has an unchanged API.
- This change removes an existing API
