Time evolution of the spectral energy distribution (SED) of the clump shown in Fig. 3. The circle markers show the fluxes of the source as identified by Hyper, whereas the diamond markers indicate the additional fluxes at 24 µm used for the bolometric luminosity calculation. The area under this SED is integrated to determine the L_bol . The optically thin fluxes at 160, 250, 350, and 500 μm are fitted to a graybody to determine the mass and the average temperature of the clumps. The results of these calculations for this clump are noted in the legend of the figure.
