Data publication: Bayesian Analysis of Hybrid Neutron Star EOS Constraints within an Instantaneous Nonlocal Chiral Quark Matter Model

The Bayesian analysis explores the EOS parameter space characterized by the coupling constants \eta_D and \eta_V, which govern diquark and vector interactions, respectively.

The provided data includes EOS tables for selected parameter sets. The coupling parameters were selected from the 60% Bayesian credibility region for physically significant cases (see figure Hybrid_EoS_Bayesian_Analysis.png), such as: • the maximum and minimum neutron star masses • the maximum and minimum neutron star onset • the most probable EOS from the Bayesian posterior This dataset enables further analysis of neutron star properties, supporting transparency and reproducibility of the published results.
