CO(3−2) channel maps of SGMC 4/5. The position of SSC B1 is marked with a cross and corresponds to the (0,0) offset position. Top panel: we present channel maps from 1440 km s^-1 to 1550 km s^-1 by 10 km s^-1. Contours start at 10σ with a spacing of 10σ, with σ = 0.39 Jy beam^-1 km s^-1 measured in line-free channels. Bottom panel: CO channel maps from 1550 km s^-1 to 1670 km s^-1 by 10 km s^-1. Contours start at 5σ with a spacing of 5σ. Offset positions are as in Fig. 4.
