pSEOBNRv4HM test of GR branch
Description
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.
