Numerical data for the computer-assisted study of an unstable Burgers–Hilbert traveling wave

This record contains numerical data used to reproduce the computer-assisted parts of the proof in the paper Linear instability of a Burgers–Hilbert traveling wave. Preprint: https://arxiv.org/abs/2605.03920 The development repository containing the verification code is available at:https://github.com/MiguelMGPascualCaballo/bhtw The data files should be placed in the supplementary_data/ directory of the repository before running the verification scripts.
