These pages are meant to complement the data and figures released within the GWTC-4 catalog with additional information produced with cWB. The results shown here are obtained with the generic burst configuration of cWB, with no specific optimization for CBC signals, and cover a subset of 23 events selected from the 218 detections in GWTC-4.0 according to the following criteria:
- at least two detectors contributing to the detection,
- the NRSUR7DQ4 waveform model was used in parameter estimation,
- network SNR > 10,
- redshifted chirp mass (1 + z) Mchirp > 15 M⊙.
Comparison between un-modeled and modeled waveform reconstructions: cWB vs CBC-PE
cWB is a wavelet-based burst method while CBC-PE is a parameter estimation method that uses the best available binary coalescence models. The comparisons shown here are performed between the cWB generic burst wavelet-based reconstruction and the CBC-PE results on the models listed in the GWTC-4 catalog.
