Contours of intensity integrated between −20 and −5 km s⁻¹ of [C II] (black contour) overlayed on false-color images of tracers mentioned in the panels. Top row: tracers of PDR gas, middle row: tracers of high-density gas, bottom row: tracers of overall gas and dust distribution in the region. The filled asterisk shows the position of CPD −59°2661. The color scale for each panel is shown next to the panel and the units are K km s⁻¹ for the spectral lines, MJy sr⁻¹ for 8 μm and Jy pixel⁻¹ for PACS (3′′ pixel). The values of [C II] contours are 10–100% of the peak intensity of 505 K km s⁻¹.
