N{\sc ote.} Source name in boldface indicates that the source is resolved at 1.4~mm with the SMA, see Sect.~\ref{sect: are the sources resolved?}.
$^{a}$~Continuum flux and position are taken from fits in the ($u, v$)~plane. Both the point-source flux~(P) and the integrated flux for a~Gaussian~(G) are shown.
$^{b}$~Calculated from the cleaned image.
$^{c}$~\citet{nurnberger:1997}. The SEST fluxes are in general higher than the SMA~fluxes, partly due to the slightly shorter effective wavelength, 1.3~mm (SEST) vs. 1.4~mm (SMA).
