Table 2:

Parameters describing the lognormal distribution of circumstellar disk masses $\mu $ and $\sigma $, from different sources.
Source $\mu $ $M_{\rm disk}(\mu)[M_\odot]$ $\sigma $
Fit to Taurus -1.66 0.022 0.74
Fit to Ophiuchus -1.38 0.042 0.49
Robinson et al. (2006)a -1.3 0.05 0.25
Ida & Lin (2004a)b -1.48 0.033 1.0
a The value given by Robinson et al. (2006) is obtained by extrapolating the observed $\mu=-2.31$ of Andrews & Williams (2005) back to the assumed initial state, and $\sigma $ is reduced to 0.25 from observed value 0.5.
b The values of Ida & Lin (2004a) are calculated using the value for the MMSN from Hayayshi (1981).
