Spatial distributions of EM of shocked Fe (red), Si (green), and intermediate-mass elements (O, Ne, and Mg; blue) integrated along the LoS (assuming the same orientation of G292) at the age of ≈ 2000 yr for model W15-2-cw-IIb-HD+dec. The solid contours mark the cuts of the forward and reverse shocks in the plane of the sky passing through the center of the explosion; the dashed lines mark the same cuts but for spheres with the centers coincident with the center of explosion (the cross) and radii corresponding to the average radii of the forward and reverse shocks.
