Hello everyone, I am excited to share **ORAC-NT** , a specialized engine I’ve developed for global gravitational wave triangulation and network stability analysis. ### Project Overview: **ORAC-NT v9: A 2PN Matched Filter Pipeline for Gravitational Wave Detection and 3-Detector Sky Localization** This framework is designed to bridge high-precision detection with robust localization across multi-detector networks. ### Key Features: - **2PN Matched Filter Pipeline:** Optimized for reliable GW signal detection. - **High-Precision Localization:** Advanced algorithms for 3-detector sky map generation. - **Stability Framework:** Tools for evaluating network performance and veto layers. - **Open Source:** Licensed under CC BY-NC 4.0 (Free for all non-profit academic research). ### Repository & Academic Record: - **Source Code:** [GitHub - Kretski/ORAC-NT-W-Stability-Framework: ORAC-NT is an analytical framework designed for real-time energy anomaly detection. It utilizes the proprietary W-Functional to quantify system stability thresholds, ranging from embedded thermal management in STM32 hardware to the identification of non-standard astrophysical phenomena and potential megastructures using NASA satellite data. · GitHub](https://github.com/Kretski/ORAC-NT-W-Stability-Framework) - **Zenodo Record:** [ORAC-NT v9: A 2PN Matched Filter Pipeline for Gravitational Wave Detection and 3-Detector Sky Localization](https://zenodo.org/records/19553825) - **DOI:** 10.5281/zenodo.19553825 I would love to get feedback from the community, discuss the 2PN implementation, or explore potential integrations with existing open data pipelines. Best regards, Dimitar Kretski ---

This is a solid and very interesting framework. What stands out to me is that ORAC-NT is not just making a broad claim — it is structured around inspectable methods: real GWOSC/LIGO data, whitening, bandpass filtering, a 2PN matched-filter chirp template, MAD-normalized SNR, detector time-delay geometry, and 3-detector sky-ring localization. I also like the W-functional extension for stability/anomaly detection. Even if some of the broader interpretations need more peer review and independent replication, the core idea of using robust statistics and stability scoring to separate meaningful signal behavior from noise or false positives is valuable. The most useful part, in my opinion, is the emphasis on falsifiability: real data, stated equations, repeatable pipeline steps, and clear comparison against published gravitational-wave timing/localization references. That makes this worth serious technical discussion instead of just speculation. Great work putting this into a public framework people can inspect, challenge, and build from. But I do caution on some claims till further validation is completed ---
