Data Release: Probing Spin-Orbit Resonances with the Binary Black Hole Population

This data release contains the analysis inputs and results for "Probing Spin-Orbit Resonances with the Binary Black Hole Population" (https://arxiv.org/abs/2502.04278). injections.pkl: This unpacks into a dictionary that includes the sensitivity injections generated for the hierarchical analyses of simulated events at O4 sensitivity. The dictionary keys are the binary parameters, the total number of generated injections, and the joint draw probability for each injection. >>> import pickle >>> injections = pickle.load(open('injections.pkl','rb')) >>> injections.keys() dict_keys(['mass_1', 'cos_tilt_1', 'cos_tilt_2', 'mass_ratio', 'a_1', 'a_2', 'redshift', 'phi_12', 'prior', 'total_generated']) hyper_pe.tar.gz: This tar file contains all the hierarchical inference results summarized in Tables IV-V of the paper, along with the 11 different simulated catalog realizations for GWTC-2 and GWTC-3. The file names specify the name of the population following the mapping below, the number of events included in the analysis, and the waveform and tilt model variations used. These are bilby result files in json format that can either be read in using json or using bilby. all_field_iso - Strong resonances (Population A - new seed, Population B - old seed) field_frac_0.64 - Strong resonances + Isotropic field_frac_1.00_wide - Weak resonances field_frac_0.00_reflect - Isotropic gwtc3_n69 - Real GWTC-3 results field_frac_0.00_o3a - The 11 different GWTC-2-sized catalogs If the filename includes "jeffreys", the Jeffreys prior was used. Otherwise, the flat prior was used. field_frac_0.00_gwtc3 - The 11 different GWTC-3-sized catalogs >>> import bilby >>> import json >>> result = bilby.core.result.read_in_result('all_field_iso_n199_mix_dynesty_simple_tilt_new_seed_reweighted_result.json') >>> result2 = json.load(open('all_field_iso_n199_mix_dynesty_simple_tilt_new_seed_reweighted_result.json','r')) old_seed.tar.gz: This tar file contains all the individual-event bilby result files in json format for the Strong Resonances Population B, along with .dat files that contain the posteriors on the spin angles evolved to f_ISCO using the SpinTaylor (PN) evolution and the surrogate dynamics, where available. They can be read in using the same commands given above for the hierarchical inference runs. new_seed.tar.gz: This tar file contains all the individual-event bilby result files and evolved posterior samples for all the other populations
