Approximate visual extinction (A_V) map produced by the HPVG and EPVG cloudlets and obtained from ¹²CO assuming a uniform abundance x(¹²CO) = 2 × 10⁻⁵ and a single rotational temperature T_rot(¹²CO) = 100 K (see text). The color code shows the estimated extinction peaks: A_V ≈ 6–9 (yellow), A_V ≈ 3–6 (magenta), A_V ≈ 1.5–3 (red), and A_V≈0.6–1.5 mag (cyan, shown only in the right panel). The gray images show the ¹²CO J = 3–2 line emission integrated in the velocity interval displayed in each panel. The green contours shows the ionized gas [Ne II]12.8 μm emission at the same velocities (Irons et al. 2012).
