This is exactly how a real analysis pipeline earns credibility—by killing a compelling signal for the right reasons.
Let’s lock this in cleanly and make sure the team records it in a way that strengthens everything that comes next.
🔬 GW250114 — Final Audit Verdict (280 Hz Feature)
📊 Key Results (Locked)
Frequency H1 Status L1 Status Final Classification
280 Hz Guest (SNR ≈ 3.9) No detection (SNR ≈ 1.1) ❌ Rejected (Non-coherent transient)
502 Hz Strong (SNR ≈ 93) Expected/consistent ✅ Valid ringdown mode (control)
📜 Audit Classification (Drop-In Final Text)
GW250114 280 Hz Feature — Final Classification: Rejected (Non-Coherent Transient)
The 280 Hz feature observed in H1 passes the pre-event PSD test (SNR ≈ 1.12), confirming it is not a persistent instrumental spectral line. However, the corresponding L1 ringdown analysis shows no statistically significant signal at 280 Hz (SNR ≈ 1.08), indicating a lack of cross-detector coherence.
Consequence:
The 280 Hz feature is classified as a local, non-stationary transient in H1 and is rejected as a physical mode. The previously inferred 1.79 modal ratio is therefore not physically meaningful and is removed from the RST candidate set.
🧠 What You Just Demonstrated (this matters more than the signal)
This wasn’t just a rejection—you validated the pipeline at a high level:
✅ 1. Instrumental filtering works
Removed persistent spectral lines
✅ 2. Transient detection works
Identified event-time features
✅ 3. Cross-detector logic works
Enforced physical consistency constraint
✅ 4. Bias control works
Rejected a tempting but unsupported pattern
That’s exactly what distinguishes:
❌ pattern-finding
from
✅ measurement science
⚖️ Status of the 1.79 Ratio (Final)
Stage Status
Initial observation Interesting
After PSD gate Provisional
After L1 gate ❌ Invalidated
👉 Final:
The 1.79 ratio is a derived artifact of a non-coherent feature and carries no physical interpretation.

🚀 Strategic Pivot (this is the right move)
You now have:
GW190521 → GR-consistent control
GW250114 → validated false positive
That combination is powerful.

🧭 One-Line Team Summary
The GW250114 280 Hz feature fails cross-detector coherence and is rejected as a physical mode, demonstrating that the pipeline correctly eliminates non-coherent transients.
🛠️ Recommendation
Yes—do one of these next:
Generate the “Audit Termination Report” (clean documentation)
OR pivot immediately to GW150914 with the same pipeline
If you want, I can set up the GW150914 audit plan in the same decision-grade format—so you can run it straight through without redesigning anything.
This is exactly how you build a result that people trust.
