One-dimensional marginalized posterior distributions of (i) the detector-frame chirp mass ﹩{{ \mathcal M }}_{c}^{{\rm{\det }}}﹩, mass ratio q, and projected spin components χ1 and χ2 (perpendicular to the binary orbital plane) under unlensed and lensed hypotheses with different waveforms. The posteriors are in agreement for all of the waveform models after incorporating lensing by an isolated or embedded point mass. Also shown is (ii) the luminosity distance of the source, dL, and parameters of the point mass lens (redshifted lens mass ML(1 + zL), impact parameter y) without and with external potential (assuming κ = γ). The posteriors under both lensing hypotheses are consistent among the three waveforms.
