Channel map of the 217.82 GHz line for mm1. Top-left panel: integrated emission between −18 and +14 km s⁻¹. The remaining panels show the channels with 2 km s⁻¹ width at the velocities marked at the top-left of each panel. The contours are the 1.3 mm continuum data in 4σ level of 0.2 mJy beam⁻¹ up to a 3 mJy beam⁻¹ level (to avoid too many contours in the center). A scale-bar is shown in the top-left panel, and the resolution elements of the line (gray) and continuum are presented in each panel. The v_lsr is at approximately − 3.6 km s⁻¹.
