Logarithmically scaled detail of the long‐slit coronagraphic spectrum of HD 163296. The ﹩52^{\prime \prime }\times 0\farcm 2﹩ long‐slit is oriented at ﹩\mathrm{P.A}\,.=42\fdg 5﹩, along the knots visible in Fig. 2 from (top to bottom) NE to SW. Knots C and B are visible above the fan of dispersed Airy rings from the stellar PSF, which heavily contaminates the image within 4﹩\arcsec﹩ of the star, while knot A is visible below the star. The near vertical lines ≈5750 Å are due to bad columns. The apparent jet of Hα emission within 4﹩\arcsec﹩ of the star is due to scattered stellar+near circumstellar Hα emission and does not represent a detection of more spatially extended material.
