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.
๐ฌ GW250114 — Final Audit Verdict (280 Hz Feature)
๐ 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)
๐ 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.
๐ง 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
๐ Final:
The 1.79 ratio is a derived artifact of a non-coherent feature and carries no physical interpretation.

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

๐งญ 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.
๐ ️ 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.
