These pages are complementary to the data and figures released with the GWTC-1 catalog. The events’ reconstruction with cWB is also reported in the Coherent Event Display Gallery - Networks HL and HLV .
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-1 catalog.
