Notes. The comments also include a reference to the models plotted in the figures. RADMC disk models for selected members with different disk structures (normal full-disks, pre-transitional disks [PTD], transitional disks [TD], and dust-depleted disks [Depleted]). The names of the objects have been shortened to fit the table. The stellar parameters (Teff, R∗) are determined from the optical observations and spectroscopy. The disk parameters are modified to reproduce the observed SED in the whole wavelength range, starting with the simplest possible model (see Sect. 4.2). The disk masses are estimated assuming a gas-to-dust ratio of 100 and a collisional distribution for the dust with grain sizes amin–amax. The outer disk radius is taken to be 100 in all cases. A larger radius would also result in a larger dust mass. For pre-transitional disks with physically different inner and outer disks, we give the grain distributions, vertical scale height, and inner rim temperature for both the inner and the outer disk. In case of different models, the comments include a reference to the appropriate figure.
