Integrated ground-state HCN ν = 0 J = 3 − 2 emission (gray scale), with |v|> 100 km s⁻¹ (with respect to the systemic velocity) contours at 0.015 × (3, 5, 8, and 13) Jy km s⁻¹. The blue contours show the approaching outflow, and the red contours show the receding outflow. The white contours show the v > 200 km s⁻¹ gas. The black line indicates the major axis of the two-dimensional Gaussian fit to the peak intensity of the continuum. The dashed black line indicates the orientation of the outflow indicated by Pereira-Santaella et al. (2016, 2020), and the arrows indicate the tentative direction of a radio elongation from Hekatelyne et al. (2020).
