Marginalized constraints on the central contrast, δ₀, and inhomogeneous size, r_b, of the ΛLTB model at the 68% and 95% confidence level. The empty contours show the constraints from the CMB, BAOs, type Ia supernovae, the local H₀, cosmic chronometers, Compton y-distortion, and the kSZ effect. The green area shows the region of the parameter space that is allowed by the standard model, here represented via the Copernican prior convolved with the CMB likelihood. See Camarena et al. (2021) for more details.
