Table 1: Observed properties of RY Tau.
Table 2: Photometric measurements of RY Tau. The data of different measurements are averaged and the standard deviation is determined. For convience, all fluxes are given in Jansky and in magnitude. Conversion factors are taken from Leinert (1997).
Table 3: Summary of the MIDI observations of RY Tau and calibrators. The dates, UT, L (in m) and PA (in degrees, measured from North to East) of the sky-projected baselines are listed. The airmass AM in the right column is given for the time of fringe tracking. The observations with a projected baseline of $79\ {\rm m}$ and $81\ {\rm m}$ provided an almost identical result (see Fig. 1).
Table 4: Parameter set for the passive disk model, the active model (Sect. ) and the active model with an envelope (Sect. 5.3). Results correspond to Fig. 6.
Table 5: Results of our $\chi ^2$ -fit presented in Fig. 7. The used method is described in Schegerer et al. (2006) in detail. The underlying continuum is estimated by a single blackbody function with the temperature T. ``RMC'' stands for relative mass contribution, ``am.-sma.'' for amorphous, $0.1\ {\rm\mu m}$ -small, ``am.-la.'' for amorphous, $1.5\ {\rm\mu m}$ -large and ``crys.'' for crystalline silicate dust grains. The crystalline component includes small and large silicate species: forsterite, enstatite, and quartz. See text for further discussion.
