SED fits to the IRAS (red diamonds), AKARI (blue triangles), and ISO data (green squares, only for HE 0433-1028 available) for each source to constrain the properties of the dominating dust component. This SED fitting technique described by Casey (2012) uses a single dust temperature graybody component (gray dashed line) and a MIR power-law component (gray dotted line) to account for the warmer dust emission, i.e., a superposition of several graybodies at different temperatures. The resulting fit curve is depicted as solid black line. The white diamonds represent the SMA upper flux limits, which have been used in the fit.
