These pages are meant to complement the data and figures released within the GWTC-2 catalog with additional information produced with cWB.

Comparison between un-modeled and modeled waveform reconstructions: cWB vs LALInference

cWB is a wavelet-based burst method while LALInference is a parameter estimation method that uses the best available binary coalescence models. The comparisons shown here are performed between the cWB wavelet-based reconstruction and the LALInference results on the models listed in the GWTC-2 catalog.

GW events reconstructed with standard settings are shown with a green badge, while those reconstructed with ad-hoc settings (e.g. ad-hoc production thresholds) are shown with an orange badge.
