Comparison of the D_d, D_Δt, λ_int, and a_ani measurements with and without the assumption of the ΛCDM model from single time-delay mock lens. The abbreviation “TD” represents time-delay information and “VD” represents velocity dispersion information. When ΛCDM model is not assumed, the internal MST (λ_int) is not constrained. When ΛCDM model is assumed, the degeneracy can be broken and hence D_Δt is constrained. The anisotropy parameter is not constrained in either case. Color-coded velocity dispersion shows that D_Δt is positively correlated with D_d but anticorrelated with σ_v. The contours represent the 68.3% (shaded region) and 95.4% quantiles.
