Spectral energy distribution of AzV 261 covering photometry from the literature from U-8.0 μm. Overplotted as a solid line is the TLUSTY model atmosphere for the best-fit stellar parmeters of T_eff = 18 000 K, log g = 2.5. The infrared-excess, corresponding to possible free-free emission of cold dust is best fit using a black-body model having T_b = 2550 K (shown as the dashed line). The dotted line is of constant frequency flux density normalized to the 3.6 μm photometry to make the free-free contribution clearer.
