Channel‐velocity maps of the CO J = 1–0 emission taken with the NMA. (a–c) Maps of the blueshifted CO emission. Each map was obtained by integrating five channels corresponding to a velocity resolution of 4 km s⁻¹. Contours are every 1.22 Jy km s⁻¹ beam⁻¹ (1.5 σ) with the lowest contours of 2.43 Jy km s⁻¹ beam⁻¹ (3 σ). The dotted contours are for negative intensity. Two crosses in each panel denote the positions of VLA 1 and VLA 2. (d) Map of the line‐center channel. Contours are every 0.61 Jy km s⁻¹ beam⁻¹ (1.5 σ), with the lowest contours of 1.22 Jy km s⁻¹ beam⁻¹ (3 σ). (e–g) Maps of the redshifted CO emission obtained by integrating five channels. Contours are drawn in the same manner as in (a), (b), and (c).
