Posterior distribution for radius of a 1.4 M_⊙ NS. The blue (orange) shaded area corresponds to the posterior obtained by applying the low- and high-density (LD+HD) filters (combined with the constraints from GW170817 and NICER). The blue and orange dashed curves are obtained by employing a unique EoS based on SLy4 until 0.16 fm⁻³, while the dash-dotted curves are obtained by employing the crust EoS based on SLy4 (green) and NL3 (magenta) until the crust–core transition. For comparison, the prior is shown by a dotted black line (see text for details).
