¹²CO J = 2 − 1 channel maps. The systemic velocity is v_sys = 109 km s⁻¹ and the channel width is 1.34 km s⁻¹. The white contours denote the 220 GHz continuum emission at 5σ, 10σ, and 15σ; the blue dashed contours represent 3σ for the smoothed extended continuum component; and the blue cross marks the stellar position. The ALMA beam is shown in the bottom left of each panel (in white). The velocities written in red italics indicate channel maps that are heavily affected by ISM contamination.
