Resulting H₀ from different mass models for a range of possible Δt_2d, 2a measurements from SN Requiem in a flat ΛCDM cosmology with Ω_m = 1 − Ω_Λ = 0.3. The median values of H₀ are shown as solid lines, and the region delineated by shades indicate the 1σ uncertainty. The relation from the LENSTOOL I model exhibits larger statistical fluctuations since image 2d is predicted in only 16% of the samples for that model (see Table E.2). The assumed 1% uncertainty on Δt_2d, 2a is achievable given the long time delay of > 3000 days.
