Notes. (a) Synthesized beam of the uniform-weighted map is $0\hbox{$.\!\!^{\prime\prime}$ }96\times0\hbox{$.\!\!^{\prime\prime}$ }77$with PA=+66$^\circ $. The rms noise level of the map is 1.0 mJy beam-1. (b) Primary beam corrected. Error in intensity and flux density as in Table 2.(c) Deconvolved sizes and PA obtained from a fit with two Gaussian for MM1-main, and one single Gaussian for MM1-S and MM1-SW. (d) Masses derived assuming a dust mass opacity coeffecient at 1.2 mm of 0.9 g cm-1 (agglomerated grains with thin ice mantles in cores of densities $\sim $106 cm-3, Ossenkopf & Henning 1994), and a dust temperature of 30 K. The uncertainty in the masses due to the opacity law is estimated to be of a factor of 2. (e) Throughout all the text, we refer to MM1-main as MM1, for simplicity.
