3D spatial distribution of Cas A shocked Fe (blue) and Si/S (green) derived from run CAS-15MS-1ETA (see Table 5). Panels (A) and (C) show the 3D distribution assuming the vantage point at Earth (the perspective is in the plane of the sky); panels (B) and (D) show the same perspective but with the vantage point from behind Cas A (namely, the perspective is rotated by 180° about the northsouth axis); panels (E) and (F) show the distribution from arbitrary points of view. The transparent image in the upper panels ((A) and (B)) is a Chandra observation showing the hot shocked plasma in the wavelength band [0.3, 10] keV (retrieved from www.nasa.gov); the transparent image in the middle panels ((C) and (D)) is a composite Hubble Space Telescope (HST) image sensitive to emission in cold O and S lines (retrieved from www.spacetelescope.org). The transparent red sphere marks the fiducial reverse shock; the transparent plane in panels (E) and (F) represents the plane where the initial Fe-rich anisotropies lie; the yellow line in panels (E) and (F) shows the direction of propagation of the Si-rich jet and counterjet. Refer to Movie 1 for an animation of these data.
