All Tables

Table 1: The name, equatorial coordinates $\alpha$ and $\delta$ (J2000), spectral type, effective temperature $T_{\rm eff}$ , surface gravity $\log g$ and metallicity [Fe/H] of our sample stars. For the model parameters we refer to De Ruyter et al. (2006). Also given is the orbital period (see references in Gielen et al. 2007; De Ruyter et al. 2006). The total reddening $E(B-V)_{\rm tot}$ , the energy ratio $L_{\rm IR}/L_*$ and the calculated distance, assuming a luminosity of L_*=5000 $\pm$ $2000~L_{\odot}$ . Distances marked with * are upper limits due to the aspect angle of the disc.
Table A.1: Best fit parameters deduced from our full spectral fitting. Listed the $\chi ^2$ , dust and continuum temperatures and their relative fractions.
Table A.2: Best fit parameters deduced from our full spectral fitting. The abundances of small (2.0 $\mu$ m) and large (4.0 $\mu$ m) grains of the various dust species are given as fractions of the total mass, excluding the dust responsible for the continuum emission. The last column gives the continuum flux contribution, listed as a percentage of the total integrated flux over the full wavelength range.
