SEDs composed of photometry data corrected (blue crosses) and not corrected (red triangles) for interstellar extinction. For the objects deemed to be foreground sources only the non-extinction-corrected data are shown. The best-fit model SED obtained from the radiative transfer calculations, input parameters given in Table 4, is given as a dashed, black line. The input stellar spectrum, approximated by a blackbody, is shown as the grey, solid line.
