Results of the SED fitting to the multiband photometry of ExtEV. The upper panel shows the absolute fluxes calculated from magnitudes given in Table 3 (dots are color-coded according to the legend). The model spectrum of the primary component is shown with a black line, its reddened versions with a red line (with additional attenuation) and a blue line (without it). The infrared excess is clearly visible and indicated by the shaded area. The middle and lower panels show the residuals from the best fit, with and without the additional attenuation, respectively. For residuals presented on the left (UV and optical range), the ordinate axes are linearly scaled while the residuals in the IR range are normalized by the model values and logarithmically scaled.
