Notes.

^(a)

The positions and diameters were estimated from the very extended configuration SMA map;

^(b)

deconvolved average diameter of the 50% contour level;

^(c)

from the rotational diagram method (see Sect. 4.1). A range of temperatures is given for those cores for which an estimate of T_rot is not possible with this method;

^(d)

mass estimated using a dust temperature equal to T_rot and a dust opacity of 0.8 cm² g^-1 at 1.3 mm (see Sect. 4.1);

^(e)

the dust continuum emission associated with core A1 and used to estimate the mass is 102 mJy (see Sect. 3.1);

^(f)

the dust continuum emission associated with cores A1+A1b+A1c and used to estimate the mass is 780 mJy (see Sect. 3.1).
