Inference on the Hubble constant H₀ and sound horizon r_s for different models (at fiducial truncation order for models 1–3), with free Ω_k, using time-delay lenses, SN Ia, and BAO. While the inferred parameters can change among models and among truncation choices, the relative discrepancy with CMB measurements remains the same. The credibility contours contain 95% of the marginalised posterior probability. The grey point corresponds to the Planck value of H₀ and r_s and to a flat Universe.
