Data and code for: The Quantum Noise Fraction and the Addressable Fraction in High-Frequency Gravitational Wave Detection

Code and data that reproduce and verify every numerical result and every figure of S. Gaudio, "The quantum noise fraction and the addressable fraction in high-frequency gravitational wave detection," Class. Quantum Grav. 43, 215005 (2026), DOI 10.1088/1361-6382/aeb348 (arXiv:2605.00053). The paper uses no measured data of its own: its inputs are constants and literature values, written in the scripts and traced to their sources in PROVENANCE_of_numbers.md. The record contains the reference verification script (verify_all_results.py, 278 checks), a check of the Goryachev-Tobar expressions against their published erratum (check_GT_erratum.py, 55 checks), audits of the figures, the three scripts that generate the figures, and the plotted values of each figure. Requires Python 3 with numpy, scipy and matplotlib; see README.md. Code: MIT License; data and documentation: CC BY 4.0. This version accompanies the published paper; no result, figure or table value changes from version 4 (see README).
