Three-color composite images showing the [C II] and [O I] 145 μm emission in different velocity channels. The orthogonal sets of lines show the cuts along which the position-velocity diagrams are derived. Left: [C II] emission in velocity interval υ_LSR = −0.5–1, 1.5–3, and 4.5–7 km s⁻¹ shown as blue, green, and red channels, respectively. The contours show the [C II] emission in the velocity interval −0.5–7 km s⁻¹. Right: [O I] 145 μm emission in the velocity intervals υ_LSR = 1–2.5, 3–4, and 4–5.5 km s⁻¹ as blue, green, and red channels, respectively. The contours show the [O I] 145 μm emission in the velocity interval 1–5.5 km s⁻¹.
