INT IDS visual spectrum (blue) and near-IR flux densities (red squares) calculated from the GAIA and DIRBE multi-epoch photometry. The horizontal bars mark the FWHM of the broadband filters. All data were corrected for extinction assuming A_V = 0.8 and the extinction law by Cardelli et al. (1989). The black curve represents the best-fit synthetic spectrum from the library of Lejeune et al. (1997), and the parameters of the model are shown in the top right corner of the plot.
