(Left panel) Spitzer 8 μm emission map of the 30 Dor region (Meixner et al. 2006) overlaid by an integrated intensity map of the ¹²CO J = 1 → 0 line (Wong et al. 2011). The contour levels correspond to 20% to 80% of the peak intensity (11.3 K km s^-1), in steps of 10%. The angular resolution of the Spitzer 8 μm and CO maps are 2′′ and 45′′, respectively. The center of the R136 super star cluster and the NANTEN2 38′′ beam are marked by a cross and a circle, respectively. (Right panel) Observed lines and corresponding Gaussian fits.
