Measurements of the dust and CO₂ gas emission in 450P’s coma. The left two panels display the dust and CO₂ gas surface brightness maps. The location of 450P’s nucleus is indicated by the cross in each image, and the panel orientations and sky-plane velocity vector directions are the same as in Figure 4. A scale bar is included in the dust image. The dust image shows elongated structure with a tail, while the CO₂ is much more symmetric. The right panel displays radial surface brightness profiles for CO₂ (solid blue line) and dust (dashed orange line) plotted against projected cometocentric distance (sunward corresponds to negative values, and antisunward/tailward corresponds to positive values of the abscissa). Each radial profile is normalized to 1 in the central pixel, and the dust profile also includes the nucleus’s contribution. For reference, the peak values of each profile before normalization are 227.95 MJy sr⁻¹ for the nucleus + dust and 3.57 MJy sr⁻¹ for the CO₂ profiles.
