Contours of the CO emission summed over 5100 − 7500 km s−1 per spaxel, as displayed separately in Appendix E, for the 12CO (1 − 0) line (contours at 4, 35, 50, and 70 mK) and the 12CO (2 − 1) line (contours at 4, 80, 120, 140, and 160 mK), overlaid on a DSS2 R-band image. The green outline shows the edge of the observed area (the extension of the contours beyond this outline is artificial).
