Notes. Column 1: source name; Cols. 2 and 3: source coordinates; Col. 4: 1.2 mm dust continuum peak flux density; Col. 5: source 1.2 mm dust continuum integrated flux density. A dash indicates that the source is too weak/blended to extract any robust physical parameter; Col. 6: source major axis, angular size uncertainties are ±1″; Col. 7: source minor axis; Col. 8: source position angle; Col. 9: source geometric radius; Col. 9: tag informing on the protostellar/starless nature of the source; Col. 10: tag informing if a source is sub-fragmented on the 8 μm extinction map. A dash indicates that the source is not seen in extinction.
