– 59 – Fig. 10.— The α$_{excess}$ (the slope of the IR excess) vs. λ$_{turn}$$_{−}$$_{off}$ (the wavelength at which the excess becomes significant) for our sample of transition disks. The masses and accretion rates are indicated by different symbols. The 4 accreting (targets #11, 2, 31, and 32) and the 2 non-accreting (targets #5 and 19) objects with α$_{excess}$ ≳ 0 are suggestive of sharp
