Model results using the revised two-belt model with the locations slightly different from the ones of Backman et al. (2009). Symbols and lines are the same as in Figure 8. In the bottom SED plot, the two warm belts are shown as the red and blue solid lines, and the contribution from the dust in the 64 au belt is shown as the brown solid line. Similarly, the sum of these three components is shown as the black dashed line.
