Panel a: overlay of the C₂H(1–0) integrated intensity map (with contours as in Fig. 2) on the CO(3–2) integrated intensity map (with color scale expanding the range [3σ, 800σ], with 1σ = 0.22 Jy km s^-1) of García-Burillo et al. (2014) in the central r = 10″ (700 pc) of NGC 1068. The (black) empty and (red) filled ellipses at the bottom left corner represent the C₂H and CO beam sizes, respectively. Panel b: comparison of the average position-velocity (p−v) plot obtained for the outflow region in C₂H(1–0) (black contours: −2.5σ (dashed contour), 2.5σ, 3.5σ, 5σ, to 9σ by 2σ, with 1σ = 0.18 mJy) and CO(3–2) (color scale: [2σ, 200σ], with 1σ = 1.3 mJy). The averaging has been done using the axes oriented along PA = 10°, 20°, 30°, 40°, and 50° (shown in a). The average outflow axis lies at PA = 30°. Blue contours represent the emission stemming from the secondary fine group of the C₂H(1–0) multiplet (group-II). Offsets along the x-axis are measured in arc seconds relative to the AGN locus. Velocity scale is measured for the strongest C₂H line at 87.317 GHz (rest frequency) and is relative to = 1136 km s^-1. The black horizontal line indicates the edges of the CO(3–2) band.
