Posterior samples and derived data products for "GW231123 as a Magnified and Diffracted Black Hole Merger"

This record contains posterior samples and derived data products associated with the manuscript “Across the Universe: GW231123 as a Magnified and Diffracted Black Hole Merger” by Srashti Goyal, Hector Villarrubia-Rojo, and Miguel Zumalacárregui (arxiv). The data products support the multi-scale gravitational-lensing analysis of GW231123 presented in the paper. They include posterior samples for unlensed, isolated point-lens, and embedded point-lens hypotheses, together with derived quantities used to produce the figures and tables in the manuscript. The analyses use publicly available gravitational-wave strain data for GW231123 from the Gravitational Wave Open Science Center, together with the associated public noise power spectral densities and calibration information released by the LIGO–Virgo–KAGRA Collaboration. These files are intended to enable reproduction of the posterior summaries, lens-parameter constraints, source-property comparisons, and derived macrolens quantities reported in the paper. The raw gravitational-wave strain data are not redistributed here and should be obtained directly from GWOSC. The associated manuscript has been accepted for publication in the Astrophysical Journal Letters. Version 2 adds the SEOBNRv5PHM posteriors (unlensed, isolated point lens, and embedded point lens with SIS macro-closure) and the SG isolated-point-lens IMRPhenomXPHM run. All nine model × waveform posteriors behind the paper's tables and waveform-systematics figure are now public, and the companion code reproduces both tables and the waveform-systematics figure from this record alone.
