Top panel: marginalised posterior distribution for the neutron-star gravitational mass as a function of radius for the models including both the low- and high-density filters. The shaded areas correspond to the 1σ, 2σ, and 3σ (from dark to light green) confidence intervals, while lines show the mass-radius relation for different selected models. The pink (blue) shaded areas represent the constraint from Miller et al. (2019, 2021) (Abbott et al. 2018) at 2σ. Bottom panels: marginalised posterior distributions for the symmetry energy at saturation, E_sym (left panel), and its slope, L_sym (right panel). The shaded rectangles show the values of E_sym and L_sym from Reed et al. (2021) (see text for details).
