Data and code release: Observation of inclination-dependent ringdown frequency shifts in 48 binary black hole mergers: 6.3σ evidence for the Semi-Dirac membrane paradigm.

Public data release accompanying the paper "Observation of Inclination-Dependent Ringdown Frequency Shifts in 48 Binary Black Hole Mergers: 6.3σ Evidence for the Semi-Dirac Membrane Paradigm" (Frederick Manfredi, 2025). Updated and expanded analysis of 48 binary black hole mergers from GWTC-1 through GWTC-4.0, yielding 6.29σ evidence for the predicted δf ∝ sin⁴ι correlation from the Semi-Dirac membrane paradigm. Includes full posterior-derived error bars and weighted linear fit. Supersedes and confirms the earlier 33-event result (10.5281/zenodo.17767545). This expanded dataset contains a processed table of 48 real LIGO/Virgo/KAGRA binary black hole events (O1–O4) with official inclination posteriors, masses, network SNR, and the predicted Semi-Dirac frequency shift δf = +0.06 × f_ISCO × sin⁴ι. It includes posterior-derived error bars on both axes and a weighted linear fit yielding 6.29σ significance (slope 2.845 ± 0.428 Hz, R²=0.580).
