* From 1.2 mm continuum (Beuther et al. 2002). They
are the geometric mean of the major and minor axes obtained from
two-dimensional Gaussian fits to the observed emission.
IRAS 20126+4104, IRAS 20216+4107 and IRAS 20343+4129 have also been observed at 850  m by
Williams et al. (2004) but they do not estimate the diameters. |
