Spectral energy distribution of HD 178219 (blue open circles) and overplotted synthetic SED from radiative transfer modeling (red dotted line) with a resulting . The line-of-sight extinction is A_v = 0.63 and the distance d = 293 pc. The photometry error bars are conservatively assumed to be 10%. The inset shows a view on the 3–25 μm region of the SED. The black dashed line is the stellar photosphere.
