CO 2–1 emission at large scales. The colorscale represents the moment 8 map from this dataset, and the magenta and cyan contours show red- and blueshifted emission from archival data with poorer angular resolution and larger LAS. Magenta and cyan contours start at 60σ (1σ = 16 mJy beam⁻¹ km s⁻¹) and follow an increase of 125σ. The yellow stars represent the position of the A and B components (see Fig. 1) and the synthesized beams are represented by white ellipses in the lower-left corner of the map.
