Spectral energy distribution for a subset of candidate members in NGC 2244. The grey line shows the observed photometry. The filled circles correspond to the observed photometry corrected by the best-fit value of the extinction, where the black circles are those used for the fitting, and the red ones were ignored due to excess emission at these wavelengths. The black triangles mark the upper limits. The orange diamonds display the best-fitting BT-Settl model value at each fitted wavelength.
