What It Is

LIGO Livingston L1 strain around GW150914. 4096 Hz; the same chirp arrives ~7 ms earlier than Hanford, opposite-sign.

Interpretation

Standard analysis sees: nonstationary / drifting. The atlas finds no named structure, but the source is distinctively extreme on Fisher Information:velocity_spectral_gini (-4.2z) — beyond what the standard bank predicts for it.
