Effects of waveform model systematics on the interpretation of GW150914
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +999
Parameter estimates of GW150914 were obtained using Bayesian inference, based on three semi-analytic waveform models for binary black hole coalescences. These waveform models diffe…
