Data release for: Eccentricity constraints disfavor single-single capture in nuclear star clusters as the origin of all LIGO-Virgo-KAGRA binary black holes

Posterior samples, pre-computed Bayes factors, hierarchical inference results, and trained DINGO neural network models for the O4a BBH eccentricity analysis. Includes data for all 85 O4a events. Code to reproduce all figures and tables: https://github.com/nihargupte-ph/o4a-eccentricity
