sensitivity at twice the spatial resolution of previous CO(1-0) observations across the 30 Doradus nebula (see Pineda et al. 2009). Higher angular resolution observations of the 30 Doradus nebula are presented in Indebetouw et al. (2013), Anderson et al. (2014) and Nayak et al. (2016), but those data do not cover the region studied here.

Near-infrared emission line imaging
-----------------------------------

We obtained nIR imaging of the 30 Doradus region in H$_2$ 2.12$\mu$m narrowband filter, and the $K$s broadband filter using the ISAAC (Infrared spectrometer and Array Camera) imager mounted on 8m Melipal (UT3) telescope of the Very Large Telescope (VLT) situated in Paranal, Chile (program ID 078.C-0487A). Toward the R136 region, the mosaic covered a field of 5$\arcmin$$\times$5$\arcmin$ area. The average seeing measured from the images is $\sim$0.8$''$–1.1$''$. Observations were taken in the ABBA sequence with the sky image 30$'$ from the stapler nebula at $\alpha$=05$^h$39$^m$01$^s$, $\delta\,=\,-$69$^{\rm \circ}$42$'$36$''$ in a region free of nebulosity within the ISAAC field of view, ensuring adequate sky subtraction. The total integration time on source was 1 hour for the narrowband filter, and 100s for the $K$s broadband filter. Data were reduced using the ISAAC pipelines, with flux calibration carried out using Persson (1998) standards.
