Different disk slopes for the objects with different spectral types. Circles mark the newly identified members, squares denote the previously known ones. Diskless objects are open symbols (none of the diskless objects is detected at 24 μm, and in general diskless objects with apparent excesses are due to contamination and/or uncertain photometry). Red symbols are the typical full-disks. Green symbols mark the TD. Blue symbols mark the PTD. Pink symbols mark the dust-depleted disks.
