Table 6:

In the upper table, we report the estimated stellar properties, and in the lower table, the stellar and disc parameters resulting from SED-fitting using Dullemond et al. (2001) model.
Stellar Parameter	value
L ( ${L}_{\odot}$ )	2.6 $^\dag$
${T}_{\rm eff}$ (K)	5520 $^\ddag$
R ( ${R}_{\odot}$ )	1.8^*
M ( $M_{\odot}$ )	1.3^**
${\rm Age}$ (Myr)	10^**
Model Disc Best-Fit Parameters
${L}_{\star}$ ( ${L}_{\odot}$ )	2.5
${T}_{\star}$ (K)	5400
${M}_{\star}$ ( $M_{\odot}$ )	1.5
${M}_{\rm disc}$ ( $M_{\odot}$ )	$5\times 10^{-3}$
${R}_{\rm out}$ (AU)	150
${R}_{\rm in}$ (AU)	0.13
Temperature of rims	1300
Inclination i	75 $^\circ$

$\dag$ From SED integration and adopting d=100 pc and A_V=1.3; $\ddag$ from the relations by Kenyon & Hartmann (1995) for a G8 V star; * from the Stefan-Boltzman law; ** from comparison with Palla & Stahler (1999) PMS tracks.
