Caption: Figure 9.
Distributions of total magnification of images S1–S4 and SX of SN Refsdal from microlensing simulations. The shape of the distributions depends on the parity of the SN image, the shear γ and convergence κ of the local lensing potential, and the mass density of the stellar microlenses listed in Tables 8 and 6. The respective vertical lines show the magnification for the parameters in Table 6 that we use to carry out our simulation. The negative-parity images (S2, S4, and SX) have significant tails extending to low magnification. We have convolved the simulated magnification maps with a circular kernel with a radius of 0.0017 pc equal to that expected for a photosphere with a velocity of 6000 km s−1 that has expanded for 100 days in its rest frame.
