The accuracy of these models for typical signals has been comprehensively assessed through comparison to NR, both in the modelling papers themselves and elsewhere (Mac Uilliam et al. 2024, e.g., [).For GW231123 we have performed the accuracy analysis in Section 4.2, and a series of targeted NR injections, which we now describe.

In order to investigate the likelihood of the presence of waveform systematics in the high total mass, comparable- mass (q >1/3), highly precessing region of parameter space, we perform a simulation study where we simulate a set of signals consisting of highly precessing NR waveforms from the SXS catalog (Boyle et al. 2019; Scheel et al. 2025) and recover with the five waveform models under consideration. From several tens of simulations, we discuss here the results from two that span the range of observed results, from unbiased parameter estimation displaying no systematics to large systematic differences between models and clear biases in parameter recovery. For both configurations, we show the total mass and mass ratio as measured in the data (the detector frame). For high-mass binaries, we expect the total mass to be one of the most reliably measured quantities.

Multimodality can arise due to the complexity of the likelihood surface when using waveform models that include higher-order multipole moments [19, 155- 157] and precession [158, 159], noise fluctuations for quiet signals [160], the presence of glitches [161-163], or there being multiple overlapping signals in the data (which is unlikely given O3 sensitivity) [164]. Therefore, multi- modality is expected in a few cases. Cases with significant multimodality are GW200208 222617, GW200308 173609 and GW200322 091133.
