a Nürnberger et al. (1997); Henning et al. (1993). b Calculated from SMA and ATCA fluxes (Gaussian fits) from this work and SEST fluxes, where available. c Disk masses estimated from ATCA fluxes (Gaussian fits), assuming a gas-to-dust ratio $\Psi = 100$, a dust opacity at 3.3 mm $\kappa_\nu = 0.9$ cm2 g-1, and a dust temperature $T_{\rm dust} = 25$ K. d Includes JCMT fluxes from Weintraub et al. (1989).
