Model predictions for SN Encore’s image positions (left), magnifications (middle), and time delays (right) for a fixed cosmological model (flat ΛCDM with H₀ = 70 km s⁻¹ Mpc⁻¹ and Ω_m = 0.3 = 1 − Ω_Λ). Each row corresponds to one lensed image, as labeled in the top-left corner of each panel in the left column. The coordinate positions are relative to the BCG in arc seconds. The black circle marks the observed image positions of 1a and 1b (left panel in first and second rows, respectively) with the circular radius corresponding to the 1σ positional uncertainty. The insets for the image positions 1a and 1b (left panels) show a zoom-in of the region near the observed image position. The time delays (in days) are relative to image 1a of SN Encore, discovered in November 2023, i.e., Δt_i, 1a ≡ t_i − t_1a.
