Asteroseismic Catalogue of 16,050 Kepler Red Giants: Δν, δν₀₁, δν₀₂ and ε

This dataset provides a machine-readable catalogue of seismic frequency spacings for 16,050 Kepler red giants, including the large frequency separation Δν, the small separations δν₀₁ and δν₀₂, and the phase shift ε, together with their 1σ uncertainties. The table corresponds to the measurements used in the accepted MNRAS manuscript “Asteroseismic Diagnostics for Red Giants with Kepler: Measuring ε and Small Frequency Separations in 16,000 Stars”. The release includes the catalogue in multiple machine-readable formats together with accompanying documentation.
