Observed median SED of T Tauri stars in Taurus (diamonds) with quartiles (gray area). Overplotted is our best-fit disk model with a turbulent mixing strength of α = 10^-4 and an accretion rate of 3 × 10^-8 M_⊙/yr (solid line). Also plotted are a model with α = 10^-2 (dotted line) and without accretion (dashed line). The gray line denotes the stellar photosphere. The inset shows the millimeter regime.
