pSEOBNRv4HM test of GR branch
This is a pipeline to do a test of GR using gravitational wave signals from binary black hole systems, where we treat the (complex) QNM frequencies as free parameters and estimate them directly from the data. The code involves changes to the SEOBNRv4HM model, where the QNM parameters are sampled over as non-GR parameters, in addition to the GR parameters. It also introduces changes to the parameter estimation code to recognise those free parameters, sample over them and plot them. We further make changes to the injection infrastructure to allow us to simulate signals with free QNM parameters.
API Changes and Justification
Backwards Compatible Changes
- This change introduces no API changes
- This change adds new API calls
Backwards Incompatible Changes
- This change modifies an existing API
- This change removes an existing API
If any of the Backwards Incompatible check boxes are ticked please provide a justification why this change is necessary and why it needs to be done in a backwards incompatible way.
This pipeline has been reviewed and used to produce results for the pSEOBNRv4HM ringdown test of GR that has gone into the O3a TGR paper. The review wiki is here: https://git.ligo.org/cbc-testinggr/reviews/nohairtesteobhm/-/wikis/home
