Integrated (220 to 250 km s^-1) intensity maps (colors, 20′′ resolution) overlayed with the contours of IRAC 8 μm. The last (eighth) panel shows a three-color image composed of CO(3–2) (blue), [C i] ³P₁–³P₀ (green), and [C ii] (red). The red lines outline the observed area. Blue asterisks in the CO(3–2) and [C ii] maps mark the positions whose spectra are shown in Fig. 2. Open blue squares and red triangles in the CO(4–3) map show the position of stars with a spectral type of O7 or earlier and O7 to B1, respectively, from Fariña et al. (2009), the filled blue star marks the position of LMC X-1, the blue asterisks are compact H ii regions (Indebetouw et al. 2004), and the red diamond marks the position of an H₂O maser (Lazendic et al. 2002).
