RRL emission as in Fig. 4 for 5–15 km s−1. Overlaid as contours are GRS ¹³CO(1–0), CHIMPS ¹³CO(3–2) and C¹⁸ O(3–2). The contours are shown for the GRS ¹³CO(1–0) emission at levels of 0.075, 0.125, 0.25, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, and 5.0 K, for the CHIMPS ¹³CO(3–2) emissionat levels of 0.45, 0.9, 1.79, 3.57, 7.13, and 14.23 K, and for the C¹⁸ O(3–2) emission at levels of 0.65, 1.03, 1.63, 2.59, and 4.1 K. The angular resolution of the data is shown in the right column. The colored beam indicates the resolution of the RRL data (16.′′ 8 × 13.′′8), with the beam of the CO emission overlayed in gray (46′′ for GRS ¹³CO(1–0) emission and15′′ for CHIMPS ¹³CO(3–2) and C¹⁸ O(3–2) emission).
