Notes. The columns are: (1) target name; (2) temperature at the target position; (3) C18O column density at the target position; (4) average temperature of the central clump (envelope); (5) average C18O density of the central clump; (6) radius of the detected central clump; (7) the mass of the central clump; (8) total mass measured inside the primary beam (45.8″); (4) appearance of the silicate feature (Green et al. 2006; Larsson et al. 2000).
