Credible intervals for the density-dependent coupling constants.

Caption

The figure tracks the scalar, vector, and isovector couplings as functions of density for the three functionals. The narrower bands in the 0.2-km case show that high-precision radius measurements strongly tighten the isoscalar sector. By contrast, the isovector coupling remains more model dependent, emphasizing that different parts of the neutron-star equation of state do not respond uniformly to improved data.
