Examples of Herschel spectral energy distributions (SEDs) for a prestellar core (left, see Fig. A.3 for the corresponding image cutouts) and a protostellar core (right, see Fig. A.4 for the corresponding image cutouts). These SEDs were constructed from the background-subtracted integrated flux densities (cross symbols) measured by getsources. A graybody fit to the SED observed longward of 160 μm is superimposed as a blue curve in both panels. Only upper limits are available at 70 μm and 160 μm for the prestellar core shown in the left panel. A single-temperature graybody rarely provides a good fit to the overall SED of a protostellar core but can nevertheless describe the SED longward of 160 μm reasonably well (cf. right panel). Similar SED plots are provided on http://gouldbelt-herschel.cea.fr/archives for all selected cores.
