Notes.
In order to estimate what the peak intensity of the SCUBA maps would correspond to in a SMA beam, we considered that the envelope follows a r−2 density profile, thus that the intensity would scale in 1/r. The SMA beam for each source is provided in Table 3. The SCUBA FWHM at 850 μm is 14″. SVS13 is not included in the table because SVS13-A and B are not resolved by SCUBA.
This high value can be explained by the very flat intensity profile of the source that is barely resolved in our SMA observations (see Fig. 3).
