Table 2: Disc mass in FUor models: column density $\Sigma $ at 1 and 10  AU from the star, cumulated disc mass  ${M_{\rm d}}$ within 10 and 100 AU, and radius ${R_{\rm g}}$ at which the disc's vertical gravity field equals that of the star. Masses are lower values and radii ${R_{\rm g}}$ upper values, obtained with a high viscosity parameter $\alpha = 0.1$.
