CO 2–1 emission at small scales. Left: maximum value map (moment 8) above a 3σ level. Center: integrated map (moment 0) above a 15σ level (1σ = 10 mJy beam⁻¹ km s⁻¹). Right: velocity map (moment 1) above a 15σ level. The white contour represents the continuum emission at 233 GHz at a 10σ value and the dashed black curves indicate the direction of the proposed streamers. The synthesized beam is represented by a filled white ellipse in the left panel.
