Median IRS spectra for T Tauri stars in Taurus (solid lines) and their quartiles (dashed lines). The upper set of spectra are the medians and quartiles for K5–M2 spectral types, the middle set represents M3–M5 spectral types, and the lower set M6–M9 spectral types. No scaling factor was applied to any of the medians or quartiles.
