ALMA maps per velocity channel of ¹³CO J = 3−2 emission in IW Car. The continuum has also been subtracted in this figure. The contours are the same as in Fig. 1: ±5, 15, 45, and 135 mJy/beam (equivalent to ±1.7, 5.3, 16.9, 47.8 K). The LSR velocities are indicated in each panel (note that the velocity resolution is higher than in Fig 1). The last panel shows the continuum emission, contours: 5, 15, 45, and 135 mJy/beam.
