Fig. 2

Velocity-channel maps of CS 2–1 emission towards G1.3. Intensities are integrated in velocity steps of 10 km s⁻¹. The central velocity is displayed in km s⁻¹ in the upper right corner in each map. The contour steps are 3σ, 9σ, 18σ, 36σ, and 45σ with σ = 0.25 K km s⁻¹. Blue crosses labelled P1–P3 indicate positions selected for further analysis.
