GWTC-2: Compact Binary Coalescences Observed by LIGO and Virgo During the First Half of the Third Observing Run

These pages are complementary to the data and figures released with the GWTC-2 catalog.


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.
