Slope of the SED from 3.6 μm to 8 μm (α_IRAC) measured by Teixeira et al. (2012) as a function of the spectral type obtained by Venuti et al. (2014), Dahm & Simon (2005), Rebull et al. (2002), Walker (1956). Symbols indicate our categorization (notation as in Fig. 4). Our sample of transition disk candidates presents dust in the inner disk similar to anemic disks, which shows that anemic disk systems can be good candidates to transition disks. Systems for which we do not have data at 22/24 μm are identified by gray filled symbols.
