Two examples of SEDs of dense cores in the Snake IRDC. Core 1 (left panel) is 24 μm dark, while core 5 (right panel) is associated with a 24 μm source. Datapoints at λ ≤ 70 μm are highlighted in red, while the longer wavelength data are shown in blue. The black, dashed lines represent the best modified blackbody fits to the data. For core 5, the latter represents the sum of the cold and warm components, where the individual fits are shown by the blue and red dashed lines, respectively.
