IRDC079.31 – overview. Upper left panel: Herschel PACS 70 μm emission and black contours present Spitzer MIPS 24 μm emission at levels of 80, 115, and 150 MJy/sr. The yellow contour shows the 3-sigma limit of the SCUBA 850 μm emission and therefore the area where we measured the clump mass. Following panels: VLA and Effelsberg 100 m Telescope data combined. Upper right panel: integrated emission of the main NH₃(1, 1) line in Jy beam^-1 km s^-1 from −0.3 to 2.8 km s^-1. Lower left panel: peak velocity distribution in km s^-1. Lower right panel: kinetic temperature in K. We extracted the temperature distribution along the black line shown in the lower right panel and plotted the values as a function of distance in Fig. 10. In each panel contours present Herschel PACS 70 μm emission at levels of 4, 8, 12, 16, and 20 mJy/px for white/black contours and 30, 50, 70, 90, and 110 mJy/px for gray contours. The NH₃(1, 1) emission peaks are marked in the upper right panel, and the corresponding spectra are given in Fig. A.2. The synthesized beam and scale are shown in each panel.
