Notes. Column (1): fragment name; Col. (2): right ascension; Col. (3): declination; Col. (4): Mass; Col. (5): effective radius; Col. (6): averaged H2 column density. Errors on the size are estimated based on the distance uncertainty. For the column density an error of 50% is assumed to take into account uncertainties related to the dust opacity (Ossenkopf & Henning 1994), data calibration (Griffin et al. 2013; Bendo et al. 2013) and dust to gas conversion. The error on the mass includes both the 50% as well as the distance uncertainty.
