Illustrative (2, 2) mode waveform showing the domains of various tests of GR performed on GW230814. The waveform is generated with typical parameters consistent with the posterior and is schematically divided into inspiral (orange), plunge–merger (light green), and ringdown (yellow). Corresponding analysis frameworks include TIGER-I/FTI for inspiral, TIGER-PI for plunge–merger–ringdown, pyRing (KerrPostmerger) for merger–ringdown, QNMRF and pyRing (Kerr/DS) for ringdown, and IMRCT, residual, pSEOB, and MDR for the full signal. Echo searches are performed in the late ringdown phase.
