Sample fit of a model SED (A1c) obtained with the MCFOST program. The lines show various contributions to the SED of the MCFOST model: direct thermal radiation (dash); diffusion (dash-dot); total (continuous) for either the stellar or the dust contributions. The symbols show the equivalent flux values in the eight photometric bands (U,...,K) for the fitted star+dust model. A model with a single blackbody for the dust appears to provide an acceptable fit to the near-infrared spectrum, even though the emitting dust spans a range of temperatures.
