Comparison of EPM and SCM distances, using the dilution factors by Dessart & Hillier (2005). Filled circles denote SNe with the explosion epoch obtained via EPM, while stars mark SNe with the explosion epoch estimated from pre-discovery photometry. The three Type II-L SNe are labelled specifically. Different colours denote the line that was used to estimate the photospheric velocities: red corresponds to Fe ii λ5169, and dark blue to Hβ. The solid line shows the relation between luminosity and angular-size distances: . ΛCDM cosmology with H₀ = 70 ± 5 km s⁻¹ Mpc⁻¹, Ω_m = 0.3 and Ω_Λ= 0.7 is assumed throughout.
