Compilation of the integrated emission in grayscale (with thin contours) from the –2 km s^-1 and –30 km s^-1 components in ¹³CO(2–1) toward the northeastern region R1 in the top and bottom panels, respectively. The thick contours outline the extinction from Kainulainen et al. (2009) in 1 mag steps between A_v of 5 and 9 mag plus additional contours of 11 and 13 mag. The integration regimes for the top and bottom panels are [–4, 2] and [–35, –24] km s^-1, respectively. The thin contours for the –4 km s^-1 map start at 1 K km s^-1 and continue in 1 K km s^-1 steps, whereas for the –30 km s^-1 component the contours start at 2 K km s^-1 and continue in 2 K km s^-1 steps. A linear scale-bar is shown in both panels.
