Integrated spectral energy distributions of the dense cores and embedded sources listed in Table 6. Fluxes are integrated within the N_1′ contour (Eq. (10)), as are the core masses and luminosities listed in Table 6. Solid lines between 3 mm and 100 μm mark the modified blackbody fits to the data points, while dashed lines only represent a logarithmic interpolation of the data points shortward of 100 μm (see Sect. 5.3).
