Type‐L Si+C dust‐scattering model densities for all flux within 50﹩\arcsec﹩ of the SN, as measured through (a) semicircular annuli centered at P.A. 0° and 180°, and (b) 20° annular wedges centered at P.A.s 90°, 135°, 180°, 225°, and 270°. Signal‐to‐noise increases with gray scale, and points with ﹩\mathrm{S}\,/ \mathrm{N}\,< 1﹩ are shown as crosses (included since our error estimates are very generous). Weighted averages measured through bins of constant ﹩\Delta ( \mathrm{log}\,r) ﹩ are shown in black.
