Notes. (a) 100 K is assumed for the warm component and 1000 K for the hot component. The derived column density and mass of the warm component depend strongly on the assumed temperature. A temperature of 150 and 200 K reduces the column density and mass by respectively a factor of $\sim $30 and 140. For the hot component 1500 K instead of 1000 K may results in a reduction of column density and mass up to a factor of 10.
(b) For the unresolved emission a source with r=50 AU is assumed to obtain an estimate of the column density.
