Overlay of the Hα, H i, and ¹²CO(2–1) emission and the dust continuum at 24 μm (MIPS), 100 μm and 160 μm (PACS) emission with contours of [C ii] at 158 μm. The white and black contours are for intensities between 10–20% (in steps of 10%) and 30–90% (in steps of 15%) of the peak [C ii] intensity of 1.18 × 10^-4 erg s^-1 cm^-2 sr^-1. The beam sizes for Hα, H i, ¹²CO(2–1), 24 μm, PACS 100 μm, PACS 160 μm, and ¹²CO(2–1) observations are 1″, 12″, 12″, 6″, 67, and 114 respectively. The H i map is integrated between –280 km s^-1 to –130 km s^-1. and the CO(2–1) map is integrated between –270 to –220 km s^-1. Marked in the 24 μm image (with black rectangles) are the regions selected for further analysis.
