Left: map of the ¹³CO integrated intensity integrated over velocities from 8 km s⁻¹ to 13 km s⁻¹. The white and orange contours show velocity-coherent components of ¹³CO emission with sizes larger than three beam sizes and the largest component, respectively. Right: map of the intensity-weighted velocity of ¹³CO in the orange contours of the left panel. The colored contours represents the Fs and IFs as shown in Figure 6. The two black dashed lines indicate position angles of 42^∘ and 55^∘, from west to north, which correspond to the criteria for separating between IF1, IF2, and IF3 (see Section 3.1).
