Critical curves of the multiple models for a source at redshift z = 1.949, which is the redshift of SN Encore (and SN Requiem). The panels show the iso_halo model in blue (all panels), PL_halo in red (left panel), iso_halo+sheet in green (left panel), iso_halo+ell_BCG in brown (middle pannel), single_plane in magenta (right panel), and baseline in orange (right panel). The best-fit model was used for each curve. The critical curves of the different models are overall similar, especially near the southern giant arc and the radial arc (of the lensed host galaxy of SN Encore), and hence the overlapping critical lines.
