Observed median SED of T Tauri stars in Taurus (diamonds) with quartiles (gray area). Overplotted is a series of disk models with varying disk mass, centered around the best fit to the median SED. The dust mass ranges from M_dust = 5 × 10^-4   M_⊙ at the top to M_dust = 5 × 10^-6   M_⊙ at the bottom, with fixed gas-to-dust ratio. The gray line denotes the stellar photosphere. The inset shows the millimeter regime.
