Contours of observed intensity ratios plotted on the intensity predictions as a function of hydrogen density nH and FUV radiation field (G0) from PDR models for the selected regions in the cloud around Treasure Chest. The horizontal dashed lines correspond to FUV in the eastern tail (1000 G0) and close to the embedded cluster (5000 G0), as estimated by Roccatagliata et al. (2013). The contours of [C II]/CO(2–1) (green), [C II]/CO(11–10) (brown), [O I]/CO(11–10) (blue), and [O I]/[C II] (red) correspond to the extreme values that these ratios (see text) take up. The ratios are inenergy units.
