Echo-delay catalogue for reflective horizon-scale structure: code, data, and figures (v2)

This repository contains the source code, processed data, and figures accompanying the manuscript: M. Devassy, Gravitational-wave echo predictions for reflective horizon-scale structure: a catalogue from GWTC posterior samples. This release provides: Python source code for computing gravitational-wave echo time delays from Kerr black-hole remnants. Implementation of detector-frame echo-delay calculations using GWTC posterior samples. Scripts to reproduce the published echo catalogue and manuscript figures. Corrected implementation (v2) addressing issues identified in the previous release, including: detector-frame redshift correction, reproducible echo amplitude estimation, corrected near-horizon approximation in the manuscript, reproducible catalogue generation workflow. Processed catalogue data. Figure-generation scripts. Documentation, software requirements, and citation information. This repository is intended to ensure the reproducibility of the computational results presented in the accompanying manuscript. It includes only research software and processed outputs; it does not contain the original GWTC posterior datasets, which should be obtained from the official LIGO–Virgo–KAGRA data releases.
