Summary of rotational temperatures for all regions sampled around the CND defined based on the CO(3-2)/CO(2-1) (left panel), CO(6-5)/CO(2-1) (middle panel), and CO(6-5)/CO(3-2) (right panel) line ratio. For each panel, the x-axis marks the region labels, while the y-axis indicates the rotational temperatures in the unit of K. The region code (along the x-axis) and color (the color of the data points) of each region match those in Table B.1. All other symbols and markers are the same as in Fig. 7.
