Posterior distributions for the polytropic index γ, speed of sound squared \({c}_{{{{{{{{\rm{s}}}}}}}}}^{2}\), and normalized trace anomaly Δ in the centers of NSs of different masses. The shaded gray region corresponds to our conformal criterion dc < 0.2, and the two-dimensional distributions on the off-diagonal panels show 68% and 95% CIs. The one-dimensional distributions on the diagonal show the PDFs of the three quantities.
