Posterior distribution for radius of a 1.4 M_⊙ NS. Left panel: blue (red) shaded area corresponds to posterior obtained by applying the low- and high-density (LD+HD) filters and matching the polytropes at 0.16 fm⁻³ (0.32 fm⁻³). The blue and red dashed curves are obtained by employing a unique EoS based on SLy4 until 0.16 fm⁻³ and 0.32 fm⁻³, respectively. For comparison, the corresponding priors are shown by dotted lines. Right panel: same as left panel, but the posterior is obtained by applying the low- and high-density filters combined with the constraints from GW170817 and NICER (LD+HD+LVC+NICER; see text for details).
