Posterior sample sets of equations of state associated with Ng et al.,"Inferring the neutron star equation of state with nuclear-physics informed semiparametric models". Both a larger prior set (1e5 samples) and four astrophysical posterior sets (1e4 samples) of equations of state are provided. The astrophysically constrained posteriors are conditioned on stacking combinations of radio pulsar observations, gravitational wave data, and NICER X-ray measurements. Within each dataset, contains the equation of state tables for each sample along with their equivalent neutron star observables. The posterior distributions generated from these samples are plotted in Figs. 2-5 of this paper. Refer to the readme for usage information.
