Reanalysis of flagged LVK events with waveform uncertainty models produces consistent spin and precession inferences across raw/deglitched data and multiple waveform approximants.
In GWTC-2.1 analy- sis, the reported values of the effective spin parame- ter areχeff = 0.25+0.10 −0.10 (IMRPhenomXPHM) and 0.14+0.17 −0.07 (SEOBNRv4PHM)
