Near-infrared spectra for disk models having ﹩{T}_{{\rm{\max }}}﹩ of 8400 K (green), 5900 K (orange), and 3300 K (blue), representing the hottest, intermediate, and coldest models considered here. The spectra are normalized at 1.67 μm. Both the overall spectral slope and the strength of various atomic and molecular features vary with temperature. We have adopted the 5900 K model in our dereddening procedure.
