Example of the morphological analysis of the molecular emission for the Hi-GAL source HIGALBM340.1288-0.1837. The upper panels show the MOPRA ¹²CO(1–0) (a) and SEDIGISM ¹³CO(2–1) (b) fitted spectra. The labels in these panels are the same as in Fig. 2. The lower panels show the channel maps at −3.4 km s⁻¹ (c), −52.5 km s⁻¹ (d), and −125.1 km s⁻¹ (e). The red ellipse is the footprint of the Hi-GAL source while the yellow ellipses are the footprints of the structures extracted by SExtractor.
