  "description": "<p>This dataset contains tabulated hybrid Equations of State (EOS) for neutron star matter, with a phase transition generated by a Maxwell construction between an instantaneous nonlocal chiral quark model for the quark matter phase and the relativistic mean field model &quot;DD2&quot; for the nuclear matter phase. 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: &bull; the maximum and minimum neutron star masses &bull; the maximum and minimum neutron star onset &bull; 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.</p>",
