Top: likelihood as a function of the distance to last scattering surface in curvature units for a locally spherical multiply-connected universe with a dodecahedral (I^∗) fundamental domain with ℛ_i = 0.31R₀. Lines are for different estimates of the CMB temperature from Planck data as in Fig. 12. In this figure, the χ_rec/R₀ parameterizes the position of the model on the geometrical degeneracy line which links H₀ and Ω_Λ with Ω_K. The degeneracy relations are approximated as Ω_Λ = 0.691 + 2.705Ω_K and . The red reference curve is for the random isotropic realization from a fiducial flat model. Vertical lines mark when χ_rec equals each of ℛ_i,ℛ_m, and ℛ_u, the characteristic scales of the fundamental domain. Bottom: zoom into the transitional region near χ_rec ≈ R_i. Both the likelihood at the best orientation of the domain versus the sky (black for the PlanckSMICA CMB map and red for the fiducial realization, as in the top panel) and the likelihood marginalized over the orientations for PlanckSMICA map (gray curve, open circles) are shown.
